;
; Change History (most recent first):
;
; <SM9> 10/12/93 RC Stop using A6 in the DefClikProc callback. Instead grad the
; teHandle from a RecoverHandle on the tePtr
; <SM8> 6/28/93 kc Init TEDoText,TERecal and TEWdBreak at TEGlobalInit time so work
; around a QuickTime bug. (Movies containing text as StartupItems)
; <SM7> 10/22/92 CSS Change some branch short instructions to word branches.
; <SM6> 10/6/92 PN # 1040150 Get rid of Sysvers conditionals and bring the code to
; the current state (7.1)
; <50> 8/11/92 SMB #1036481 <gbm>: #1036481 <gbm>: Removed font/keyboard
; synchronization for Roman-only systems. It's unnecessary and
; slows things down!
; <49> 7/15/92 SMB ## <ys>: Renamed DoText selectors: teMark is now teHighlight and
; teLoc is teCaret.
; <48> 7/8/92 PKE Fix up previous comment (I was too quick with the Return key).
; <47> 7/8/92 PKE #1035214 <csd>: Fix DoSearch so that it always exits by calling
; FreeFmtOrderArray at exit, which will dispose of any fmtOrdering
; handle and clear the ExpandMemRec.emFmtOrderHFlag flag which
; says that the handle is valid. This will prevent subsequent
; calls from thinking they have a valid handle before they
; actually allocate one.
; <46> 7/7/92 PKE #1030684 <yds>: TEGetPoint failed in multiline text if a R->L
; script was present because in this case DoMeasure measured from
; the beginning of the buffer, not the beginning of the current
; line. Fixed.
; <45> 6/23/92 SMB #1029263,<pke>: Now checking the script's 'itlb' flags to
; determine if the keyboard and font should be synchronized. Added
; new IM 2nd Ed. routine names to the file for easier searching of
; routines.
; <44> 4/27/92 DTY Get rid of hasSplineFonts conditionals.
; <43> 4/20/92 YS #1027783, a wrong label @1 instead of @3 caused the wrong jump,
; and the stack was not cleared, causing the registers not to be
; restored.<43-YDS-4/19/92>
; <42> 4/3/92 YS #1025998, in TextBox, when trying to find the right line highet
; in systems that use associated font (see <41>), saving and
; restoring of the font saves a LONG (instead of a word) creating
; the problem of loosing the port font. Another connected problem
; was the way Script Manager handeld those privete verb calls in
; the roman. This was fixed in the Script Manager. <42-YDS-4/2/92>
; <41> 2/6/92 YS #1014691, Cube-E, In the old days, the Hebrew/Arabic extention
; used to calculate the highet of a script font as Max(script font
; size, associated font size). The problem with that is that if
; you use style runs, like styled TE & WP's, you can't get the
; real size of of a script font, and you allways have the
; associated font size in it. The universal one byte init no
; longer handles it. TE will calculate it itself if it is: 1)
; unstyled text. 2) script font. 3) Has associated font (other
; then 0). <41-YDS-2/6/92>
; <40> 2/4/92 YS #1015382, Cube-E, don't redraw the whole line for a left 2 right
; system when justification is teForceLeft. <40-YDS-2/5/92>
; <39> 1/30/92 YS #1018683, Cube-E: TextBox should handle #teForceLeft correctly
; and not set it to #teJustLeft allways. <39-YDS-1/30/92>
; <38> 1/13/92 PKE #1019673, Bruges: Unstyled TE should not sync the keyboard at
; all for smEastEurRoman script.
; <37> 12/17/91 PKE #1017647: Fix keyboard synchronization in unstyled one-byte
; non-Roman text. For bidi scripts: don't synchronize control
; chars and L-R numbers, set keyboard to Roman for other L-R
; chars, and sync keyboard to font for R-L chars. For other
; scripts: sync keyboard to font for script letters, set keyboard
; to Roman for Roman letters, and don't sync anything else.
; <36> 12/12/91 DCL #1009157: Changed a Tst to Tst.b so as not to test the potential
; garbage in the other byte. Changed procedure noClickProc in
; TextEdit.a, StyledTextEdit.a, and TextEditPatchIIciROM.a
; <35> 11/12/91 JL fixed the broken build. The previous change had a <34> after an
; EndIf with no comment marker - - ooops! The build was broken for
; a day and no one complained.
; <34> 11/12/91 SMB #1014705 - for CubeE and Bruges. Keyboard and font synch'ing
; isn't correct for punctuation and numbers: TE allows a Roman
; keyboard & a non-Roman font combination for ascii characters and
; european characters (or high ascii chars.) and it should also
; allow this for numbers and punctuation marks. This was reported
; against the Eastern European systems. Actually, this code will
; be optimized to only allow this unsynchronized state for a
; 2-byte fontScript and a Roman kbd. See ClickKeyboard2Font. Also
; fixed some bugs in the synchronization of the font & kbd for
; unstyled text in TEClick and TEKey.
; <33> 9/30/91 YS Used to syncronize the keyboard wrong for L->R scripts
; (unstyled) when was backspacing a selection (and not a single
; delete), d6 wasn't set up corectly. use teSelStart(a3) instead.
; (bug #1013159) <33-YDS-10/1/91>
; <32> 9/23/91 PKE For Cube-E (and Bruges): If non-Roman scripts are installed,
; TEInit should no longer set TESysJust to its idea of system
; default, since users can now set the default. Also: Define
; forLocalizability here if it is not defined in BBSStartup.
; <31> 9/13/91 YS Rolled in the fixes made for SS-6.1.
; <31p> Fix the wrong placment of the caret for one blinking cycle when
; changing a language and typing a char. (bug #1006971)
; <31p-YDS-8/27/91>
; <31n> when backspacing, sync the keyboard to the right language enen
; for unstyled (single byte only). (bug #1006972) <31n-YDS-8/27/91>
; <31m> Fix the Big cursor bug, this is NOT the old big applelink cursor
; bug (fix YSD <3.1>). In the case where the cursor is on a line
; start, we used to fall into the single caret code
; (but we didn't have any split caret !!!), so while switching
; the cursor rect's for a single caret, we used to garbage the
; selRect. so, we now test ExpandMemRec.emTwoCursorsFlag in this
; case to avoid it. (bug #1007065) <31m-YDS-8/27/91>
; <31l> Fix TEGetPoint for styled TE for R->L scripts, used to asume
; that if we are on a begining of a style run, the width is 0, and
; if we are on the end, we should TextWidth all of it, which is
; not true for R->L scripts. (bug #1007067) <31l-YDS-8/27/91>
; <31k> Added support for a single caret while handling an Arrow (left
; or right) key, for styled L->R text. have to change the Keyboard
; in a different way to support the corect display of a
; single caret. <31k-YDS-8/27/91>
; <31j> Fix in xStyleGuts, don't change font's when their are not from the same
; script, has a minor fix in SetGuts to.(commented) <31j-YDS-8/27/91>
; <31i> Fix DoMeasure for Right to left text in unstyled TE, in order to
; support fix <31h> for unstyled, use _Pixel2Char instead of
; MeasureIt. <31i-YDS-8/27/91>
; <31h> Fix TEGetPoint Bug for Right to left text, use DoMeasure
; instead of MeasureIt. <31h-YDS-8/27/91>
; <31g> Synch Keyboard to click even with an unstyled TE record,
; this is not only a nice thing to do, but very importent when
; handling a single cursor on a bi-direction script, if we
; would like your single-split carret to be displayed
; correctly. <31g-YDS-8/27/91>
; <31f> when click on script boundry, take care of the next cursor
; update, has to do with the split carret stuff. This was fixed
; in SetKeyboard2Font and ClickKeyboard2Font.<31f-YDS-8/27/91>
; <31e> find where the click was (to define the right script).<31e-YDS-8/27/91>
; <31d> Support for a single carret, this supports the styled
; TE part.<31d-YDS-8/27/91>
; <31c> Added support for a single carret, it will expand & shrink
; the the right part of a cursor to show only "one" cursor,
; depending on the language, so we will gwt a moving cursor
; (when switching scripts). this supports the unstyled TE part.<31c-YDS-8/27/91>
; <31b> using the byte after the TwoByteCharBuffer in teDispatchH for
; fixes <31c> and <31d> (lastScript), so change the place it clears
; so only a word will be cleared there (instead of a long).<31b-YDS-8/27/91>
; <31a> Fixing Hebrew/Arabic AppleLink bug that causes a big cursor:
; the right way! this fix is in four places.<31a-YDS-8/27/91>
; <30> 4/3/91 SMB jdr,#86089: (also, pke) Fixing appl-crashing bug in
; NewRomanFindLine - should be clearing the high word of d0 before
; doing a long operation. Shows up when applications use
; TEHitTestHook and have multiple styles on a line.
; <29> 2/14/91 SMB pke,#70628: Unfortunately, forced to remove support for Forward
; Delete that was added in <20>. Conditionalizing it out so it can
; be added again later. See <29>.
; <28> 2/14/91 SMB pke,#82817: After Dark and Chooser string clipping bug -
; NewRomanFindLine's dependency on _NPixel2Char takes into account
; the caret width when determining linebreaks. This 1 pixel
; difference caused strings that were 1 pixel too long to no
; longer completely display since the linebreak occured in a
; different place. The problem was that the measurement occured on
; the character boundary (after the final character of the string)
; and the leading edge value returned was F. TextEdit deals with
; these results by backing up one character to guarantee that all
; characters completely display when drawn. In the case of calling
; _NPixel2Char this is not necessary since it will still return
; the correct results and TextEdit will behave correctly based on
; these results. So, to fix this problem we no longer subtract one
; for the caret width before calling _(N)Pixel2Char.
; <27> 2/14/91 SMB pke,#DTS FT: Quit trashing a4 across Hook calls!
; <26> 2/11/91 SMB pke,#SMB-2/9/91-1: TextEdit didn't always erase characters when
; deleting them. Another symptom of this same bug is that TextEdit
; didn't line break at a CR. The problem was that when TE looked
; ahead for blanks at the end of a line in NewRomanFindLine, it
; skipped over blanks, CRs and any other character whose value was
; <=$20. Now it checks each breaking character for a CR and once
; found, forces a line break there.
; <25> 2/11/91 SMB jdt,#TEBug.ReCaLines: KanjiTalk bug fix in ReCalLines - need to
; back up 2 bytes for correct redrawing of double-byte text.
; <24> 2/11/91 SMB pke,#OYDBB002: Fixed the MathCad (application) bug in
; NewRomanFindLines by ckecking for a dummy style run at the end
; of the StyleRun array whose startChar = endChar.
; <23> 2/1/91 SMB pke,#HIG-JS-048,#81519,#82169: In NewRomanFindLine: testing for
; a blank at a line break before calling TE's FindWord routine.
; Fixed problem with styles in balloons: was comparing a final
; result to the linestart in d6, but it was modified for styles,
; so needed to compare to actual value saved in lineStart(a6).
; Fixed performance problem: change in algorithm caused unstyled
; TE to call TextWidth on the entire document (pinned to each
; lineStart) when determining line breaks. Major slowdown! Are now
; calling _NPixel2Char instead of _TextWidth & _Pixel2Char in TE's
; Pixel2Char routine (TEHitTestHook). Should make TE FAST(er)!
; Renamed leftSide to leadingEdge in P2CFrame and added
; WidthRemaining member (see TextEditPriv.a).
; <22> 1/22/91 SMB (pke) Re-fixing bug #68221. The previous fix required calling
; OutlineMetrics for the whole font in order to get an ascent &
; height in TextEdit. This wasn't acceptable due to reformatting
; problems. So, the code to support OutlineMetrics has been
; removed and we are now turning off PreserveGlyph before drawing
; in order to draw squished characters when their ascent or
; descent is larger than the font's metrics. GetFontInfo will
; still be used to get ascent & height, as in the past, and we
; will be backwards compatible although not pretty.
; <21> 1/18/91 SMB (pke) Fixed bug # 62963 - No longer preserving a3/a4 across
; DumpBuffer routine. Saving a3 caused a dangling ptr and it's not
; necessary to save a4. Also, added a call to DumpBuffer in
; TEDispose in case an app never calls TEIdle (which empties the
; buffer). Changed _NewHandle call in GetHandle to allocate the
; handle in the System heap in order to prevent orphaning the
; handle when an application quit without emptying the text
; buffer. ¥ Also fixed a linebreaking bug in Pixel2Char - wasn't
; calling DoubleByte with the correct offset (was using the offset
; for the line not the offset w/in the whole text buffer thus
; far.)
; <20> 1/14/91 SMB (jdt) ¥ Fixed bug #66732 & #57858: if the scrap handle parameter
; (newStyles) in SetStylScrap was NIL should do nothing and exit.
; ¥ Fixed bug #58512: Must lock scrap handle in InsRsrved before
; calling PstStylGuts since PstStylGuts expects to use the handle
; again after moving memory. Also fixes bug #65043. ¥ Fixed bug
; #77962: TE was determining line breaks by measuring words rather
; than style runs for a Roman-only system. This was causing
; drawing to be significantly different than the measuring when
; FractEnable was on or a scaled font was used. Rewrote code (now
; called NewRomanFindLine) to do the right thing! ¥ fjs fixed bug
; #70628: adding forwardDeleteChar support in TEKey so that this
; function key on the extended keyboard works. ¥ Fixed bug #67699:
; StdTxMeas did not detect overflow when measuring long lines, so
; the widths returned to TE in this case were small, causing TE to
; write all the text on one line. StdTxMeas was modified to keep
; the last count and width before the overflow. This info is used
; to call _Pixel2Char to get the correct character offset for line
; breaking. ¥ Fixed bug #66900: TextBox did not clip text
; correctly for long words due to the incorrect use of _P2C's
; LeadingEdge flag. See changes in TE's P2C and DoSearch. ¥ Fixed
; bug #68221: did not calculate the ascent & descent of an outline
; font correctly if preserveGlyph is true. Now calling
; OutlineMetrics for this. See routine GetOutlineMetrics and the
; routines calling it, TextBox & GetSize. ¥ Fixed Finder bugs
; #80728 & 75607: in StdEntry, for unstyled text, save the
; grafport's font info before setting the TERec's style info into
; the grafport.
; <19> 12/15/90 SMB (gbm) KT bug: Only draw line in ReCalLines when wordRedraw is <1.
; Added support for another gestalt selector, gestaltTE5, for the
; new TextWidthHook.
; <18> 10/30/90 SMB Fix text buffering bugs: must preserve register containing
; ExpandMem ptr around a call to another procedure. Also, moved
; code that dumps the buffer in SetFont2Keyboard after determing
; that synchronizing was necessary. Then, must test for an empty
; buffer in TEBufferText after the SetFont2Keyboard call and after
; a full buffer has been dumped. Using hasBufferingFix conditional
; for these changes. Added TextWidthHook to dispatch table and the
; internal interface which uses the hook, TETextWidthHook to hook
; out the TextWidth calls to keep our developers happi(er)!.
; Renamed nTEWidthHook to ScriptChar2Pixel. Using hasTextWidthHook
; conditional for these changes. Moved frame for TextBox into
; TextEditPriv.a Added teFUseTextServices to comment although TE
; doesn't use it. This allows an application to disable inline
; input. The teFInlineInput bit will be used to enable the
; features added for Inline Input. This bit is set by the inline
; input service and may also be set by a developer who desires
; these features even when inline input is inactive.
; <17> 9/13/90 BG Removed <15>. 040s are behaving more reliably now.
; <16> 9/11/90 SMB Fix teCROnly bug that crashes the system: pre-incrementing
; caused us to compare one too many in the text and then the +1 to
; point beyond the CR caused the line breaks to be one off. Moved
; InlineInput test into TESetSelect instead of ClickKeyboard,
; since never want to call KeyScript while doing inline. If in
; Inline, then not hilighting to the EOLs anymore, only to edge of
; text (see InvrtRectangle). Modified highlighting code to modify
; the middle rectangle line by line in order to call highHook for
; Inline. Moved HiliteFrame into TextEditPriv.a.
; <15> 7/25/90 BG Added some EclipseNOPs for flakey 040s.
; <14> 7/25/90 SMB NEEDED for SS-6.0.5, SIXPACK & 7.0: Fixed Hebrew/Arabic
; scrolling down bug - caused selRect's top & bottom values to be
; negative which caused a BIG caret to be drawn. Fixed in
; CaretInsideRun.
; <13> 7/10/90 SMB NEEDED for 7.0 & SIXPACK: Must export GestaltTEVersion.
; <12> 7/10/90 SMB NEEDED for 7.0 & SIXPACK: Oops! Moved GestaltTEVersion back into
; here for SIXPACK+ builds from TextEditInit.a.
; <11> 6/22/90 SMB NEEDED for 7.0 & SIXPACK: Moved TEGlobalInit, GestaltTEVersion
; and its vectors to TextEditInit.a. Exported routine labels for
; TextEditInit.a. NEEDED for SS-6.0.5, SIXPACK & 7.0: fixed Arabic
; line end bug for unstyled text, where the system slowed down
; because was reading off the end of the line starts.
; <10> 6/11/90 SMB NEEDED FOR SIXPACK & 7.0: Added Inline Input bit to
; TEFeatureFlag and support for it in ClickKeyboard2Font.
; <9> 5/29/90 DDG NEEDED FOR SIXPACK: Changed all the sixpack conditionals from
; six-point-oh-seven to six-point-oh-six.
; <8> 4/27/90 SMB NEEDED for SIXPACK - Fixed old bug for old FindWord: when using an
; application's teWordBreak routine must save d1!
;*********** End of SS-6.0.4 f4 (for KanjiTalk 6.0.4 only!) changes ******************************************************
; <7> 3/20/90 SMB NEEDED for 6.0.5 and SS-6.0.4 - Added call to SetKeyboard2Font
; in TEKey (rather than DelGuts, see 1/16/90) for script systems;
; whenever backspacing over a script boundary the keyscript wasn't
; updated. Bug #59422. - In TEBufferText, must set d0 to the
; current position before calling SetFont2Keyboard (in case of a
; kbd change while buffering)
; <6> 2/18/90 SMB NEEDED in 6.0.5 - DoSearch didn't work correctly if the
; TEHitTestHook had been replaced. We needed to check a
; terminating condition when hooked out: the high word of d0 was
; set T if found a char offset.
;*********** End of domestic 6.0.5 changes; SS-6.0.4, SS-6.0.5 and 7.0 changes still occurring ***************************
; <5> 2/13/90 SMB NEEDED for 6.0.5 - Fixed broken TEWidthHook by putting back in
; the old C2P code and adding a new hook nTEWidthHook for the SMgr
; compatible C2P.
; <4> 1/30/90 SMB NEEDED FOR 6.0.5 - multiple bugs fixed: see history below.
; 1/30/90 smb - Fix in TEKey so that when the current position is at a line end and
; the height of the current line is > the height of the next line, the
; down arrow will put the caret on the next line. Bug #53697.
; 1/30/90 smb - Fix to PtToLine to leave the line # negative when going up on the
; top line. Makes DoFind do the right thing. Fixes bug 35646: up-arrow
; key doesn't get to beginning of text.
; 1/29/90 smb - No longer call SetFont2Keyboard for DumpBuffer.
; - Added patch to DoCaret to pin the caret in view when
; blanks exceed the edge of the view rect.
; 1/26/90 smb - Before synchronizing the font to the keybd, dump the text buffer: user
; could change the keyboard in the middle of buffering. (see TEBufferText and
; SetFont2Keyboard)
; 1/25/90 smb - Call HideCaret for up & down arrows to erase the old caret before
; setting teLftCaret in TEKey. Fixes bug #52887!
; - Fixed up arrow bug, #51967, that caused the caret to move up multiple
; lines according to the size of the largest font on the current line.
; - If zero width in DoSearch, want to branch ow this one pixel difference
; causes the caret to display on the wrong line ending. Roman fix.
; Bugs #58921,59247.
; 1/24/90 smb - Found bug in DoSearch where needed to setup a2 as current line again.
;*********** End of SS-6.0.4 f3 (for Arabic and Hebrew 6.0.4 only!) changes **********************************************
;*********** Did not add humane scrolling or move the equates (see 1/22-1/23 comments) for SS-6.0.4! *********************
; 1/23/90 - Changed FindWord branch for linebreaking to 'bge' instead of 'bgt'.
; emt - Added humane scrolling (slower) to DefClikProc (also see TEClick).
; 1/22/90 - Moved private equates and frames into TextEditPriv.a.
; 1/16/90 SMB NEEDED FOR SS-6.0.4 and 6.0.5 - (added 1/22/90 to Scripts604 build)
; Added call to SetKeyboard2Font in DelGuts for Script Systems:
; whenever backspacing over a script boundary the keyscript wasn't
; updated. Bug #59422.
; Reorg beginning of FindWord in order to be compatible with applications
; using incorrect char breaking algorithms for Script Systems.
; <3> 1/16/90 SMB NEEDED FOR 6.0.5 - Fixed bug in TEGetPoint, added double-byte
; buffer at end of dispatch record, fixed bug in r-to-l processing
; of caret that showed up when scrolling down.
; 1/15/90 smb Fixed Hebrew/Arabic scrolling down bug - caused selRect's top & bottom
; values to be negative which caused a BIG caret to be drawn. Fixed in
; CaretInsideRun.
; 1/9/90 smb Using private space in TEDispatchRec for buffering of a double-byte
; char rather than using ExpandMem as a global buffer which can affect
; any active TE record. This fixes a bug seen in KanjiTalk (AppleShare)
; when an application uses two TE records. Buffering in one record can
; be dumped into the other record due to the global storage space not
; knowing which record it applies to.
; 1/8/90 smb NEEDED FOR 6.0.5: bug 58823, TEGetPoint returned incorrect values
; when there's no text in the TERec.
; <2> 1/4/90 PKE NEEDED FOR 6.0.5 (smb's changes from SS-6.0.4b23 to SS-6.0.4f1):
; ¥<15Dec89smb> Set the offset parameter to non-zero for
; StyledLineBreak for unstyled text. ¥<17Dec89smb> Preserve
; register d2 in HiliteMiddle. ALSO: Changed conditionals from
; (Scripts604 | SysVers >= $700) to (Scripts604 | SysVers >=
; $605). Updated header to BBS format.
; <1> 12/18/89 CCH Adding for the first time into BBS.
; BBS versions above:
;___________________________________________________________________________________________________
; EASE versions below:
; <3.2> 12/11/89 smb See history of bug fixes below dated Nov. 22, 1989 -> Dec. 7,
; 1989.
; 12/7/89 smb Fixed problem with setting the boundaries in ChkBounds. Also set
; boundary in DoDraw based on WordRedraw rather than teSysJust.
; ¥ Corrected test of teForceLeft in iTEGetPoint.
; ¥ Fixed bug of a large cursor (#52888) due to RomanFindLine (really
; StylMeasure & P2C) incorrectly increasing the char count due to
; an invalid leftSide flag set in TE's P2C. This caused ReCalLines
; to read beyond the end of the line heights record. Fixed by
; setting a flag which said to ignore the leftSide flag if TextWidth
; did the measuring in P2C.
; 12/6/89 smb Unconditionalized code in VisibleLength to fix a LR line w/ R
; justification display bug. Mark was right!
; ¥ Set flags in caret display code to indicate when in the middle
; of a style run but on a line end (see CaretInsideRun).
; ¥ Fixed bug in {hit-down on,cursor movement to} a script boundary
; to set the keyboard to the preceeding style run rather than the
; succeeding one. (see calls to ClickKeyboard2Font).
; ¥ In BufferChar & DumpBuffer backed up one offset posn to get
; previous style run for SetFont2Keybaord call.
; 12/5/89 smb Fixed LR highlighting bug at line ends; in InvrtRectangle.
; 12/3/89 smb Added a new keyboard/font synchronization routine to be used
; when doing a hit-down which allows a Roman keyboard with a
; non-Roman font, specifically because KanjiTalk wants to enter
; Roman text from a Japanese font.
; ¥ Fixed potential bug in TESetStyle: must test the doFont bit in
; the mode since it's possible for the mode to be an additive
; combination of styles.
; ¥ Use application font for SetFont2Keyboard rather than system
; font.
; ¥ Have to use emBufferPtr for a flag to indicate when I
; unsynchronize the font & keyboard in ClickKeyboard2Font. These
; will be used to keep SetFont2Keyboard from synchronizing the
; font & keyboard when trying to paste a character in this
; unsynchronized situation.
; ¥ Also had to add a call to ClickKeyboard2Font from TESetSelect in
; order for horizontal cursor movement to work correctly in this
; new unsynchronized situation.
; 11/26/89 smb More cursor movement pinning, this time in GetStyleEnd. Also,
; need to use the high caret rectangle in TEKey rather than always
; using the teSelRect!
; 11/22/89 smb In CursorMovement had to pin the style run to the line end for
; correct position.
; <3.1> 11/21/89 smb See history of bug fixes below dated Oct. 4, 1989 -> Nov. 20,
; 1989.
; 11/20/89 smb Added a test in ptchGetRLPosition because when processing a CR
; entered at the EOD, the current line (a2) is the next line. This
; causes TE to look beyond the end of the lineStarts array.
; 11/17/89 smb Bug in DumpBuffer for unstyled textEdit: screwed up stack since
; was popping the stack w/o doing the push! Now doing the push as
; well!
; 11/16/89 smb Fixed TrimMeasure for unstyled TE. Also moved the firstStyleRun
; and secondStyleRun to the top of the the FmtOrderFrame.
; 11/13/89 smb Bug fix for buffering 2 byte text on Kanji! see DumpBuffer and
; TEBufferText.
; 11/8/89 smb Moved secondStyleRun and firstStyleRun from SharedFrame to
; FmtOrderFrame since TextFrame needs this info for XTrimMeasure
; changes.
; 11/6/89 smb Fixed buffering bug in BufferChar & TEKey; must set emBufferLen
; non-zero when buffer the 1st byte of a 2-byte character.
; 11/1/89 smb Adding call to GetStylesInOrder in order to call VisibleLength
; for a line's style runs. We need to traverse the style runs in
; display order but backwards!
; 10/31/89 smb Fixed TETrimMeasure to call VisibleLength at the appropriate
; times for unstyled text: LineRect uses the line direction and
; justification to determine when to call it.
; 10/26/89 smb Bug fix in FindWord for Chinese Script System: clear
; fwLeadingEdge flag!
; 10/16/89 smb Added updating of outlined region in TEUpdate.
; 10/6/89 smb Had to clear (a2) in iTEFeatureFlag so that the return result
; was set right for an initial state of clear (vs. set).
; 10/4/89 smb Removed LRTextFlag since it's based on WordRedraw. Will tst
; WordRedraw instead!
; <3.0> 10/12/89 smb Checked in fix below dated 10/3/89.
; 10/3/89 smb Fixed the caret display in TEActivate and TEDeactivate for
; outline highlighting. Put in old DoHilite code for Roman systems
; for HyperCard outlining.
; <2.9> 9/26/89 smb Checked in fixes below dated 8/31/89-9/19/89, plus: Saving the
; bit in the upper byte of the ExpandMemRec.emBufferLen word.
; 9/19/89 smb Adding Outline Hilighting to TEActivate/TEDeactivate.
; 9/17/89 smb Fixed TEKey to turn off and reset the text buffering bit around
; the StdEntry call.
; 9/15/89 smb Must move newTEFlags into a data reg for modulo 32 bit ops
; (bset,bclr,btst).
; 9/14/89 smb Added calls to dump the text buffer in StdEntry and TeKey.
; 9/12/89 smb Fixed up DumpBuffer and TeFeatureFlag code.
; 9/6/89 smb Removed call to SetFont2Keyboard in TEKey since I added it to
; BufferChar.
; 9/5/89 smb Complete rewrite of SetFont2Keyboard.
; 9/2/89 smb Fixed bug #52736, CursorMovement should jump 2 bytes for Kanji
; on a RL line. Had to also add call to SetFont2Keyboard in
; BufferChar since changing the styled teRec's initial kbd setting
; (from Roman to Japanese) before entering Kanji text caused the
; character to display incorrectly. It was using the initial
; setting in the style run array, rather than synchronizing the
; font to the current keyboard before displaying.
; 8/31/89 smb Fixed TEKey bug: when returning from BufferChar should branch
; signed rather than unsigned. Also fixing bug in SetFont2Keyboard
; to always modify the Rsrved font if it exists. Both fixes for
; bug #51962.
; <2.8> 8/30/89 smb NEEDED FOR 604 Script Systems AND BIG BANG ...(see additional
; comments below dated 7/31/89 - 8/29/89)
; 8/29/89 smb Fixed Roman RL hiliting. Wasn't hiliting correctly for line
; ends. See MeasureWidth. (added to SS-6.0.4 and 7.0 PTCH!)
; 8/25/89 smb Fixed Kanji word dragging bug, #51603, by comparing the char
; offset to the Left anchor and setting the leadingEdgeFlag
; accordingly. (added to SS-6.0.4 and 7.0 PTCH!)
; 8/19/89 smb Fixed another unlocked handle bug. Similar to bug #51602. Made
; d3StyleRun(a6) and d4StyleRun(a6) offsets rather than pointers.
; See OnSameLine. (added to 6.0.4 PTCH!)
; 8/10/89 smb Added one more fix in teKey for arrow keys to work after a
; hit-down on the R. end of a line. (added to 6.0.4 PTCH!)
; 8/8/89 smb Added Gestalt function. (added to 6.0.4 PTCH!)
; 8/7/89 smb Fixed bug #51640 - the hyphenation bug - the right way in
; FindWord. When RecalLines calls FindWord on a Roman system
; should use the old FindWord code. (not added to 6.0.4 PTCH!)
; 8/5/89 smb Fixed multiple cursor bug, #51602 - was saving a ptr to the
; styleRun array in a2StyleRun(a6) (see teGetFormatOrder) when the
; handle to the styleRec wasn't locked! Oh-Dopey-Me! ANY memory
; movement could cause this bug! Fixed in GetNextDisplayStyle,
; DoSearch, TEGetFormatOrder by saving it as an offset, and then
; restoring it to a ptr when I need it. This is just for styled
; text. I save it as a pointer for unstyled text since I create it
; myself (see GetFormatOrdering). (added to 6.0.4 PTCH!) Fixed bug
; #51961 - striking an up/down arrow key after a hitdown at either
; line end caused the caret to display at the opposite end of the
; line rather than the previous line. This bug occurred because
; teKey was inappropriately setting teLftCaret to T. It should
; only be set initially if the key was not a cursor key. (added to
; 6.0.4 PTCH!)
; 8/4/89 smb Fixed Roman line breaking bug, #51677 - must incr to the next
; char posn in StylMeasure when the LeftSide flag from P2C is
; False. RomanFindLine expects the result back to be a LeftSide
; hit, not a rightSide hit! (added to 6.0.4 PTCH!)
; 8/2/89 smb Added SMgr VisibleLength code. (added to 6.0.4 PTCH!)
; 8/1/89 smb In yesterday's fix I had a bug in swapping d2 around a test of
; the CCs. Fixed by saving d2 and restoring it w/ a "movem" which
; won't affect my CCs!
; 7/31/89 smb Fixed an Arabic highlighting bug that occured by having an
; arabic word followed by a long Roman word that forced a
; linewrap. The problem was that code was added to TE's C2P to use
; TextWidth for hit-test on line ends rather than SMgr C2P.
; However, it should still use SMgr C2P for hiliting and it
; wasn't. So, fixed it so it would! (not added to 6.0.4 PTCH!)
; <2.7> 7/25/89 smb NEEDED FOR 604 Script Systems AND BIG BANG É (see comments below
; dated 7/17/89 - 7/24/89)
; 7/24/89 smb ConcatStyles should only be called in DelGuts for a styled
; record. Oops! NOT ADDED TO 604 AURORA PTCH: Cleanup of nEqu.d
; file: renamed nStyle to nStyles, as it should be.
; 7/21/89 smb Added ConcatStyles to DelGuts - when it deletes a style it
; doesn't check to see if the two adjacent styles are the same.
; Found this in Arabic.
; 7/20/89 smb Before using an existing NullStyle in SetFont2Keyboard must make
; sure the font's script is the same as the keyScript. Otherwise,
; use script's default font.
; 7/19/89 smb Fixed Roman FindWord hyphenation bug. Problem was occurring
; because RecalLines used the SMgr-compatible FindWord for
; determining a word boundary but when it called FindLine for the
; line break, FindLine used the oldFindLine code (RomanFindLine)
; which used the old FindWord code. This inconsistency caused
; RecalDraw to only redraw the second line where the word
; following the hyphen was to be displayed. It needed to also
; redraw the first line where the first half of the hyphenated
; word existed. There was also a problem with "where" the second
; part of the hyphenated word was being displayed on the next
; line. Because performance dictated the need to use the old
; FindLine code for Roman systems, we can't easily fix these
; problems. The best and easiest fix for this is to always use the
; old FindWord for all of Roman word breaking needs. Removed code
; from RomanFindLine that said the caller of FindWord was
; RomanFindLine. It's no longer necessary.
; 7/18/89 smb TEInit fix: replaced d1 w/ d3 for WordRedraw determination, and
; fixed loop incremental. Replaced call to AltSetRsrved in
; SetFont2Keyboard to SetRsrved. Changed in v2.2.
; 7/17/89 smb NOT ADDED TO 604 AURORA PTCH: Cleanup of branching in DoMeasure.
; NOT ADDED TO 604 AURORA PTCH: Faster clearing of d0's high word
; in FindLine.
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; 6.0.4 patches and 7.0 ptch0 from here up ;;;;;;;;;;;;;;;;;;;;
; <2.6> 7/13/89 smb NEEDED FOR AURORA! (see comments below dated 7/3/89-7/12/89)
; 7/12/89 smb Misc. cleanup after code review.
; 7/10/89 smb Cleaned up TEFeatureFlag routine, and added another feature bit,
; teFForceScriptFont (to be used in SetFont2Keyboard for Script
; Systems).
; 7/7/89 smb Fixed bugs for Arabic and Kanji.
; 7/5/89 smb Fixed dummy run bug in DupStyle - had fixed in PstStylGuts but
; then I broke inserting a style in the middle of another style,
; and in fixing this discovered an easier fix to the original bug!
; 7/3/89 smb Moved vector initialization above SMgr init code in TEInit in
; order to boot script systems before they are enabled. (They were
; calling TENew, and since vectors weren't initialized it was
; crashing.)
; <2.5> 7/9/89 smb Moved include of ScriptPriv.a back into casm statement! V2.4
; broke my ROM build. Since ROMS and System files are built from
; this file, I had to modify the System patch file for TE instead.
; <2.4> 7/8/89 smb Moved include statement for ScriptPriv.a out of a casm statement
; for Big Bang build.
; <2.3> 6/30/89 smb NEEDED FOR AURORA! Mucho worko accompli! (see comments below
; dated 6/19/89 - 6/30/89)
; 6/30/89 smb Fixed bug in TEInit code for setting wordRedraw in order to use
; on Script Systems.
; 6/29/89 smb Fixed signed/unsigned bugs. Added vectors. Misc. clean up,
; performance improvements, and bug fix.
; 6/24/89 smb Fixed problem of a dummy run being created in DupStyle when only
; one style was being pasted. For more than one style, fixed the
; problem by calling ConcatRuns in teStyleInsert, InsRsrved,
; DelGuts, and PasteGuts. Cleared out ExpandMem space that I use.
; Misc. bug fix and clean up.
; 6/23/89 smb Fixed many direction bugs: teSysJust and wordRedraw problems.
; 6/20/89 smb Fixed Arabic lineEnd bugs in C2P. Was breaking highlighting and
; hitdown.
; 6/19/89 smb Fixed obscure measuring bugs for Arabic in DoMeasure and
; GetWidth. Was breaking display of two adjacent Roman fonts on an
; Arabic SIS w/ RL line direction.
; <2.2> 6/13/89 smb Check-in (see comments below dated 5/30/89-6/12/89)
; 6/12/89 smb Fixed FindLine to work w/ Peter's correct version of
; StyledLineBreak. Fixed script run boundary bug in FindWord.
; Added TEFeatureFlag interface and activated buffering code (was
; casm'd out.
; 6/8/89 smb Fixed RomanFindLine to call the old FindWord code rather than
; the SMgr FindWord code.
; 6/7/89 smb Modified CaretDisplay code for RL text by calling new
; GetDirection rather than GetStyleDirection.
; 6/5/89 smb Finally found the style run bug: problem was caused by
; subtracting two pointers to get a length; one of the pointer had
; the high byte set; fixed by calling StripAddress. Fixed for
; other guilty code!
; 5/30/89 smb Added direction of font to high-order byte of stFace in the
; array of stElements for performance. Also added TEFeatureFlag
; interface for outline highlighting and text buffering.
; <2.1> 5/30/89 smb Check in (see comments below dated 5/16/89-5/23/89)
; 5/23/89 smb Fixing FindWord problems for double-byte text by replacing a
; huge piece of logic with some simple statements for determining
; the leadingEdge flag for SMgr's FindWord. Also fixed some bugs
; in FindLine for MultiScript and Kanji systems.
; 5/17/89 smb Must lock the StScrpHandle for SetStylScrap to work correctly:
; see bug #36986.
; 5/16/89 smb Had to reset A2 to selStart(a3) in TECopy after a NewHandle
; call, which may have invalidated the pointer to the teRecord
; (upon which A2 was based!). See bug #46036.
; <2.0> 5/13/89 smb Added back in mods for v1.8. Also fixed more bugs: see comments
; below dated 5/12/89-5/13/89.
; 5/13/89 smb In TE's P2C had to test if pixelWidth passed in was = to
; TextWidth's result; if so, done. Exit w/o calling SMgr's P2C.
; Fix for bugs #47756,48159.
; 5/12/89 smb Had to save a1 in FindLine before calling GetEnvirons since
; RecalLines depended on it. Also added FindLineRegs to old
; FindLine for this.
; <1.9> 5/5/89 smb Backed out v1.8!
; <1.8> 5/5/89 smb Check in (see comments below dated 5/2/89-5/5/89)
; 5/5/89 smb Added the old FindLine code back in for Roman text: performance
; hit!
; 5/4/89 smb Bug fix in DoSearch: hit-test on line ends wasn't correct for
; Arabic SIS. Fix for HyperCard bug 47857: clicking at the left of
; a line was placing the cursor at the end of the previous line.
; Needed to add a test for CR in order to fix this.
; 5/2/89 smb Changed branch condition after test of teCROnly. Fix for bug
; 39276: changed add operation in TECustomHook from a long op to a
; word op.
; <1.7> 3/29/89 smb Misc. bugs fixed: see comments below dated 3/17/89-3/21/89
; 3/21/89 smb Bug fix: should be a word op and not a long op!
; 3/19/89 smb Bug when number of lines in a teRec is zero, but lineStarts
; array still contains values from previous times. Either first
; two words in array should be zeroed or should always test for
; teNLines(a3) before accessing these words. (in RecalLines)
; 3/17/89 smb Another TEFindLine bug in CRonly mode: branching on exit to the
; wrong label.
; <1.6> 3/15/89 smb Double-byte char fix in BufferText.
; 3/15/89 smb Fixed teCROnly bug in FindLine - was returning one character too
; soon.
; 3/13/89 smb Broke out the common part of TextFrame, SharedFrame, and Cursor
; Frame and created FmtOrderFrame. Bug fix for Cobra II! Left
; cursor key at the beginning of a teRecord wraps to the end of
; the teRecord! Fix in DoubleByte.
; 3/12/89 smb More synch'ing problems: must use nullStyle if it exists in
; SetFont2Keyboard; Also fixed a bug in TeKey for
; SetFont2Keyboard, to use the style of the char previous to the
; selection start/end. This will handle the case of being on a
; format boundary.
; 3/10/89 smb Fixed problem in synch'ing Font 2 Keyboard: needed a pointer to
; ExpandMemRec.emNewFont for SetRsrved.
; 3/6/89 smb Performance enhancements; called FixFormatEnd for problem of
; last style run in record.
; 3/4/89 smb Fixed bug in BufferChar; wasn't saving 1st byte of double byte
; char in the correct place in ExpandMem.
; <1.5> 2/22/89 smb Removed casm flags from code in RangeRect since included all
; configurations!
; <1.4> 2/19/89 smb Removed rom casms (see comment below) and removed extraneous
; routines not being used due to my new code. If needed can back
; up a version or two.
; 2/17/89 smb Removed Rom casms that I added yesterday.
; <1.3> 2/17/89 smb Check in; see comment below.
; 2/16/89 smb Fixed bug in TEInit: reset a0 w/ ExpandMem address after calling
; StripAddress. Also adding Rom casms for pre-Cobra II roms to use
; TE code that's not Script Manager compatible,
; <Not(NuMac|HcMac|MacPP)>. Also fixed bug in TEBufferText,
; although it's code not being used yet.
; <1.2> 2/15/89 SMB Merged System File version with Rom version + added code to make
; TE Script Manager compatible (see non-EASE comments below dated
; 31Aug88SMB and later)
; <1.1> 11/10/88 CCH Fixed Header.
; <1.0> 11/9/88 CCH Adding to EASE.
;___________________________________________________________________________________________________
; old EASE versions:
; <1.7> 11/2/88 GGD Got rid of machine specific conditionals in favor of feature
; based conditionals.
; <1.6> 10/27/88 PKE added script manager support in teinit.
; <¥1.5> 9/23/88 CCH Got rid of inc.sum.d and empty nFiles
; <1.4> 9/6/88 BBM changed routine names, so they would not conflict with mpw
; includes.
; <1.3> 5/2/88 RWW Fixed last-minute System Tools 6.0 bugs - caretHook was never
; being called, and Pixel2Char was being called directly in one
; place instead of TEHitTestHook.
; <¥1.2> 3/25/88 RWW Fixed bug in iTEGetHeight when no characters in buffer.
; <¥1.1> 3/16/88 RWW Roll-in of System Tools changes
; <1.0> 2/11/88 BBM Adding file for the first time into EASEÉ
;___________________________________________________________________________________________________
; non-EASE/pre-EASE versions:
; 2/13/89 smb Fixed bug in FindLine, where I wasn't adding the finalLength to
; the overall length of the line.
; 2/1/89 smb Modified TeKey for textBuffering, but casm for a later build.
; Also defined new bits in the newTEFlags field (long) in the
; TEDispatchRec: bit 0 = teFAutoScr (already being used as such,
; just made a constant) and bit 1 = teFBuffText. Added ExpandMem
; calls, and removed equates that have been moved to ToolEqu.a.
; Added ExpandMemRec in place of with/endwith pair around all uses
; of ExpandMem fields.
; 1/25/89 smb Modified SMgr calls for MPW 3.0 Equates.
; 1/24/89 smb Fixed a bug in hiliting for unstyled text. Was wiping out my
; fake style run array when I hilited the left end of the line,
; and before I used it for the right end of the line.
; 1/21/89 smb Removed ChkBounds fixes since didn't appear to be working with
; them.
; 1/20/89 smb Modified CursorMovement to remove unneccessary code and to
; branch correctly.
; 1/18/89 smb CodeReview mods: added FreeFmtOrderArray. Modified ChkBounds,
; added R-to-L test for TrimMeasure, and reorganized
; formatOrdering code.
; 12/21/88 smb Fixed teDrawHook bug: at entry, a4 was not the handle to the
; teRecord as documented. Replaced Lo3Bytes code in FindWord with
; _StripAddress. Added code to keep the high caret in view
; (TESelView+) when split cursors occur.
; 12/13/88 smb Modified GetRLPosition routine to correctly display split
; cursors. The rule is to display the high cursor at the script
; run whose direction corresponds to the line direction
; (downstream flow), and the low cursor at the script run whose
; direction is opposite of the line direction (upstream flow).
; 12/9/88 smb Added new conditionals and creating one file for Rom and System
; File builds.
; 12/5/88 smb Modified teHiliteText to work correctly for mixed directional
; text. Must pin not only to style run but also current line. 
; Results from SM HiliteText vary due to line direction; Modified
; PixelWidths to call C2P with the offsets returned. Cleanup all
; this new code for unstyled text. Fixed FindLine bug that caused
; a crash when adding new styles that forced a line wrap.
; 11/29/88 smb Fixed FindLine code to use the correct parameters for script
; changes when calling StyledLineBreak. Added a routine,
; ConcatRuns, to clean up the styleRun array. A null run (not
; entry) was being added to the array the first time a style was
; added to the teRec (this is after the default run is set up.)
; Also fixed a bug in SetOneStyle. Was creating the initial run
; with a length of teLength rather than teLength+1.
; 10/25/88 smb In DoMeasure, changed test for reverse order from TESysJust to
; WordRedraw. Added code for caret positioning. Also synched the
; keyboard to the font and the font to the keyboard.
; 10/25/88 smb Find correct WordRedraw value in TEInit; fixed GetWidth to
; measure with TextWidth when trying to measure a whole line or a
; complete style run, otherwise to measure with Char2Pixel. This
; fixed the problem of the selRect falling outside the right edge
; of the view rectangle when TESysJust is set R->L. (23Sept) Fixed
; the selection problem in Pixel2Char when TESysJust is set R->L.
; Rewrote highlighting code now that I can see the right results
; for display and hiliting. (25Oct) GetFormatOrder was added to
; display style runs correctly on a line.
; 8/31/88 SMB ALTAIR enhancements: changes made to FindLine, FindWord, and
; DoHilite to call SMgr routines to get the job done. Also added a
; new routine GetCurScript to return the current script at a given
; character position for a styled teRec. Renamed routines (by
; adding an 'i' for internal) due to MPW name collisions in the
; rom.
; <S508> 8/2/88 RWW S508 revisited, since it got copied over. Figured out a much
; simpler method of handling the problem (handle being
; dereferenced over a call to InstallIntDispatch which could
; thrash the heap) involving only a one line change - calling
; MyNewHandle instead of _NewHandle.
; 6/27/88 SMB ALTAIR Changes: Incorporate changes to support different script
; systems in order to be SMgr compatible. East Asian support and
; left-dominant Middle Eastern complete. Changes made in:TEInit,
; Pixel2Char, Char2Pixel, TeKey, MeasureIt. Added DoubleByte and
; BufferChar.
; <S425> 3/16/88 RWW Fixed bug in TEContinuousStyle and changed the way it handles
; face attributes
; <PMAB387> 2/10/88 DBG Fixed bug in TEDispose where dispatch vector was not getting
; released for unstyled TE records.
; <PMAB381> 2/4/88 RWW Took out some redundancies and moved autoscroll flag from its
; position in "teFlags" (nŽe teRecBack) to the new dispatch
; record. Ooops. It acted as a high bit set in the new handle to
; the TEDispatchRec
; <C971> 11/4/87 RWW Yanked SetEraseFlag and associated logic. Only bought us about
; 10% - not enough to get excited over. Added TECustomHook to give
; a high end way to stuff new internal dispatch table addresses
; <C971> 11/3/87 RWW Added new internal dispatch table to (quasi-) support tabs. We
; won't officially support tabs, but these hooks will make the job
; a lot simpler for those who need it. (It used to be a lot easier
; to hook in tab support than it is now that styles have to be
; reckoned with.)
; <C971> 10/30/87 RWW Added some hysteresis to lineStarts hack, to try to prevent some
; heap thrashing from constant SetHandleSize calls
; <C971> 10/29/87 RWW Changed fail test in SetGuts to masking uninteresting bits Added
; doToggle functionality to SetGuts, StyleGuts, SetRsrved,
; CheckMatch
; <C971> 10/28/87 RWW Changed branches to optimal form. Those patches marked
; "<C971/RWW102887>NO" are for new ROMs and total replacement
; patches only. (There were an awful lot of word branches where
; shorts would do!) Added SetStyleScrap
; <C971> 10/27/87 RWW Changed references to faces to be byte instead of word length
; <C971> 10/26/87 RWW InitRsrved had some strangeness in it Added TESetEraseFlag and
; TEContinuousStyle. Added in code to check for erase flag before
; performing _EraseRect's
; <C971> 10/23/87 RWW Broke out some common code, trying not to reinvent the wheel:
; AnyNullStyle, GetTrueStyle, GetOneStyle Changed GetStylScrap to
; return a proper scrap record, even if there is no selection
; range. Prevents apps from having to special case insertion
; points Rewrote most of TEGetHeight to properly sort and pin
; start/end Added conditional inclusion of TEDispatch'ed routine
; addresses so I can find them without a Cray
; <C971> 10/22/87 RWW Patched ReCalLines to properly shrink lineStarts array
; <C971> 10/21/87 RWW Added conditional equates to make RAM-based testing easier
; <C971> 10/19/87 RWW Fixed 0 length bug in TEStylInsert
; <C971> 10/12/87 RWW Did some personal cleanup. Added new equates for new structures.
; Changed Bcc's and Bcs's to more logical forms. Began comparing
; various patches against this source to resolve differences.

; <C851> 4/27/87 MBK Miscellaneous bug fixes (search on 851 to get more detailed
; descriptions); added code to handle setting styles on null
; selections.
;
; ** BETA 8 from here up **
;
; <C815> 2/13/87 MBK Fixed StdEntry to set the Grafport's txMode from TERec.teMode.
; Fixed RangeRect to set pnLoc correctly for compatibility with
; old applications. Fixed FindLine to check for a CR at the end of
; a string of unwrapped blanks.
; <C788> 2/11/87 MBK Fixed TEStylInsert to get the input parameters in the correct
; order.
; <C766> 2/5/87 MBK Fixed CopyStyle to lock my style handle before calling PutScrap.
; Fixed DelGuts to relock text handle after munging. Removed call
; to StdEntry from TEStylInsert because TEDispatch does it.
;
; ** BETA 6 from here up **
;
; <C734> 1/30/87 MBK I changed PutStylScrap to TEStylInsert, which unlike
; PutStylScrap will insert the text as well as the style info.
; Fixed StyleGuts to check for point sizes <= 0 when an addSize is
; done. It now converts such values to 1. Modified TEGetHeight to
; subtract 1 from startLine because GetLineHites wants it 0-based.
; SetStylHandle fixed to dispose of old style handle before
; setting new one.
;
; ** BETA 5 from here up **
;
; <C719> 1/29/87 MBK I removed the C717 change to SetHiteAscent. The ptr there was
; not an offset from styleTab, it was an addr on the stack.
; <C717> 1/28/87 MBK Made changes in GetDefStyle, DoDraw, MeasureIt, StylMeasure,
; SetHiteAscent, and SetStyle to protect unlocked pointers from
; memory reallocation. Added startLine and endLine input to
; TEGetHeight. Added RecalDraw to PutStylScrap.
;
; ** BETA 4 from here up **
;
; <C676> 1/23/87 MBK Added GetStylScrap, PutStylScrap, TEGetPoint, and TEGetHeight.
;
; ** BETA 3 from here up **
;
; <C622> 1/13/87 MBK Changed to clear the color highlight bit only if a highlight
; hook has not been installed (this was a problem with
; highlighting in the hex editor of ResEdit). Modified DoErase to
; erase the previous character if the mode is XOR, otherwise
; redrawing it will wipe it out (this was a problem in NetTrek).
; Modified StylMeasure to lock the style Record so that
; dereferenced pointer doesn't end up pointing to garbage. Also
; fixed Pixel2Char to do a signed comparison on the stack space.
; This bug was discovered by tEx, when the RAM cache was set high.
; <C597> 1/6/87 MBK Restore A3 ptr after RGBForeColor call in StdExit, in case TERec
; gets moved.
; <C574> 12/30/86 MBK Fixed SetStyle to save D2 on the stack because _RGBForeColor
; destroys it. Fixed Pixel2Char to restore D0 from D1 if NewPtr
; has to be called.
; <C513> 12/12/86 MBK Changed to clear bit in HiliteMode instead of setting bit in
; pnMode for color hilighting. Fixed selection bug in Pixel2Char.
; <C485> 12/4/86 MBK Set the error code in D0 before calling SysError. Fixed bug in
; which carets left on the screen were not getting erased (in
; Mac3D).
; <C475> 12/2/86 MBK Set the high bit of the pnMode before highlighting, to use the
; new background color highlighting method.
; <C454> 11/21/86 MBK Fixed bug in RangeRect that caused selection to be off in
; MultiPlan. Fixed special case in which line redraw did not work,
; in RecalLines.
; <C440> 11/19/86 MBK Fixed SetLineHite to take the line height from the only style
; when text length is 0 (instead of using the system font as a
; default). Fixed RecalLines to consider the next character the
; start of the next line if the width of the viewRect is less than
; the width of a single character. Fixed styleGuts to access
; FmDefaultSize as a byte, not a word. Fixed RecalLines bug in
; which lines are not recalibrated when text is typed over a
; single CR.
;
;--------------------------------- ROM 77 from here up ----------------------------
;
; <C393> 11/10/86 MBK Fixed CopyStyle and InsertRecal to reset ptr values after a
; memory allocation call (the ptrs were pointing to trash).
; <C381> 11/8/86 MBK Made all changes resulting from code review.
; <C229> 10/29/86 MBK Fixed 2 register preservation problems. Fixed InsertRecal memory
; overload problem. Redesigned method of updating line heights.
; <C207> 10/16/86 MBK Fixed problem in which CR at bottom of ViewRect did not cause
; scrolling (cleaned up DefClikProc, which fixed the problem seen
; in the Poke program). Changed Pixel2Char not to expect a buffer
; ptr as input, and to allocate the space itself on the stack.
; Added StylTextBox. Changed scrpStartChar to a LONGINT. Changed
; TECopy and TEPaste not to touch the desk scrap if the TERec is
; an old one (since David G. mentioned a lot of old applications
; may need to preserve the desk scrap for Undo). Changed DoHilite
; back to what it was (except with middle lines being highlighted
; as a block for speed) because the International version was just
; too slow; this means I also removed the HiliteText hook.
; Modified RecalDraw to adjust the redraw selection according to
; changes in line height.
; <C182> 10/6/86 MBK Changed colorBit to clrBit since colorBit is a Quickdraw Trap
; already. Modified DoHilite to always measure from start of line,
; to fix highlighting problem with scaled fonts. Got rid of
; special code in PasteStyle to prevent style duplication, And
; just call ConcatStyles at the end. Added DoErase to fix italics
; erase problem. Removed code to shrink style runs array in
; ConcatStyles. Fixed problem of not clearing flag bits in ptrs
; before doing operations on an address. Changed color from
; LONGINT to RGBColor, and added Ernie's RGBForeColor and
; GetForeColor to handle this for the Alladin world.
; <C139> 9/10/86 MBK Fixed TEGetStyle to return the grafport settings for records
; without style. Made addSize OR'able in StyleGuts. Fixed "index
; expected in D0" bug in DoSearch. Added DoMeasure, ChkBounds, and
; made FindLine call Pixel2Char for International. Fixed
; word-wrapping with spaces. Put local equates back in this file
; and put the rest of the equates in nToolEqu.a. Got rid of scrp
; equates, since they were the same as the st- equates.
; <C105> 9/3/86 MBK Renamed TEGetStyle to GetStylHandle and TEFindStyle to
; TEGetStyle. Added SetStylHandle. Added TEDispatch to handle All
; style traps (except TEStylNew) with only 1 real trap for them
; all. Made the following changes for International: added the
; Pixel2Char, Char2Pixel, and HiliteText hooks; modified doSearch
; and doDraw to test TESysJust and perform their functions
; backwards if it's set; totally rewrote DoHilite. Added
; NextLineRect to speed up DoDraw. Rewrote stages 2 and 3 of Recal
; for speed. Added new feature of Not resetting the line heights
; in Recallines if the high bit of the line height already stored
; is set. Changed the TESetStyle and TEReplaceStyle input modes to
; be OR'able. Also combined the body of these 2 routines for
; efficiency. Added stuff to compute distance to be auto-scrolled
; for TERecs with style, in DefClikProc. Changed BSET and BCLR of
; handles to _HLock and _HUnlock.
; <C95> 8/4/86 MBK Fixed the scrolling problem in SelView; Modified Recallines to
; take into account changes in point size.
; <C94> 7/29/86 MBK Added 3 more traps (TEReplaceStyle, TEGetOffset, TEFindStyle);
; renamed TEGetStyle to TEFindStyle (TEGetStyle now returns the
; style handle); fixed selection bug, the problem was in
; ScanMeasure and DoSearch. Fixed bug in CharByChar. Started
; fixing recalibration problem.
; <C78> 7/17/86 MBK removed equates to an external file; added four new traps
; (TEStylNew, TEStylPaste, TESetStyle, TEGetStyle); added the
; following new routines: SetOneStyle, GetDefStyle, ScanMeasure,
; GetLineHites, GetHite, CopyStyle, DeleteStyle, DecStyleCount,
; StylMeasure, SetLineHite, PasteStyle, MakeRoom, DupStyle,
; FindStyle, CompareStyles, AddStyle, ExtendStyle, FindLineHite,
; GetCurStyle, GetNumStyles, GetStyle, RecalstStarts,
; SetHiteAscent, SetStyle, ConcatStyles, ChangeStyle, and
; FindFeature; modified the following routines: TESetText,
; LineRect, PinDisplay, StdEntry, TECopy, DelGuts, RecalDraw,
; FindLine, RecalLines, SetLineArray, TEPaste, InsGuts, TEKey,
; TEPinScroll and TESelView.

; To Do:
; Remove extraneous code from NewRomanFindLine. Marked with (XX).
; There may be a measuring bug using TextWidth, due to StdTxMeas' use of pnLoc. TE doesn't seem to

; modified <2/8/90smb>
; This internal interface still uses TextEdit's old Char2Pixel routine
; for backwards compatibility for developers. Specifically, if a developer
; has been using this interface, and chains his routine in, the new Char2Pixel
; routine would have broken his application. We now have a new interface,
; ScriptChar2Pixel (below) that allows a developer to replace our new
; Char2Pixel routine or chain with it instead.
;
; However, if a script system is installed, we override this hook and
; automatically use the new hook. Also, if a developer has not replaced our
; internal measuring routine (OldChar2Pixel) then we use the new routine.
; Hence, the only time we use the OldChar2Pixel code is when a developer has
; used this hook. <2/8/90smb>

; FUNCTION TEContinuousStyle(VAR mode: INTEGER; VAR aStyle: TextStyle;
; hTE: TEHandle): BOOLEAN;
; ** <C971/RWW102687> **
;
; This function gives you information about the continuity of
; various aspects of the current selection. The result
; returned is TRUE if the given style exists across the
; entire selection range. The style attributes to check
; are specified by the mode parameter, which takes the
; same values as in TESetStyle. Attributes which are
; continuous across the current selection range are
; returned in aStyle, with the appropriate bits set in
; mode. If the selection range is an insertion point,
; this call duplicates TEGetStyle, except that the returned
; style reflects the style of the _next_character_typed_.
; The attribute bits of aStyle.tsFace are individually
; checked across the selection range, and are returned set
; to 1 if that attribute is indeed continuous.
