; This file is included in PatchIIciROM.a.
;
; Change History (most recent first):
;
; <51> 8/11/92 SMB #1036481 <gbm>: Removed font/keyboard synchronization for
; Roman-only systems. It's unnecessary and slows things down!
; <50> 7/15/92 SMB ## <ys>: Renamed DoText selectors: teMark is now teHighlight and
; teLoc is teCaret.
; <49> 7/8/92 PKE Fix up previous comment (I was too quick with the Return key).
; <48> 7/8/92 PKE #1035214 <csd>: We would like to fix DoSearch so that it always
; exits by calling FreeFmtOrderArray at exit, which will dispose
; of any fmtOrdering handle and clear ExpandMemRec.emFmtOrderHFlag
; which says that the handle is valid. This will prevent
; subsequent calls from thinking they have a valid handle before
; they actually allocate one. However, this fix is too risky; so
; instead we modify DoText to always clear the flag so that no
; routine thinks it has a valid handle when it doesn't. The more
; correct fix is in TextEdit.a.
; <47> 7/7/92 PKE #1030684 <yds>: TEGetPoint failed in unstyled 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.
; <46> 6/23/92 SMB #1029263,<pke>: Now checking the script's 'itlb' flags to
; determine if the keyboard and font should be synchronized.
; <45> 4/27/92 DTY Get rid of hasSplineFonts conditionals.
; <44> 4/3/92 YS #1025998, in TextBox, when trying to find the right line highet
; in systems that use associated font (see <43>), 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. <44-YDS-4/2/92>
; <43> 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). In this file we do a 'come from' patch to GetFontInfo,
; one patch is from TextBox and the other is from GetSize
; <43-YDS-2/6/92>
; <42> 2/4/92 YS #1015382, Cube-E, don't redraw the whole line for a left 2 right
; system when justification is teForceLeft. <42-YDS-2/5/92>
; <41> 1/30/92 YS #1018683, Cube-E: TextBox should handle #teForceLeft correctly
; and not set it to #teJustLeft allways. Had to add a ptchTextBox
; for that. <41-YDS-1/30/92>.
; <40> 1/13/92 PKE #1019673, Bruges: Unstyled TE should not sync the keyboard at
; all for smEastEurRoman script.
; <39> 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.
; <38> 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
; <37> 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 2-byte
; text. See ClickKeyboard2Font. Also fixed the synchronization of
; unstyled text cases in TEClick and TEKey.
; <36> 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) <36-YDS-10/1/91>
; <35> 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.
; <34> 9/13/91 YS Moved in 6.1 fixes for a Localizable 7.0.1 (forLocalizability)
; <34p> Fix the wrong placment of the caret for one blinking cycle
; when changing a language and typing a char. (bug #1006971)
; <34p-YDS-9/2/91> <34o> Fix the problem of the arrow keys not
; functioning in a L->R system, with line direction R->L (bug
; #1007934) <34o-YDS-9/2/91>. <34m> when backspacing, synch the
; keyboard to the right language even for unstyled (single byte
; only). (bug #1006972) <34m-YDS-9/2/91> <34l> 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) <34l-YDS-9/2/91>
; <34k> 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) <34k-YDS-9/2/91>
; <34j> 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. <34j-YDS-9/2/91>
; <34i> Fix DoMeasure for Right to left text in unstyled TE, in order to
; support fix <Y8> for unstyled, use _Pixel2Char instead of
; MeasureIt. <34i-YDS-9/2/91>
; <34h> Fix TEGetPoint Bug for Right to left text, use DoMeasure
; instead of MeasureIt. <34h-YDS-9/2/91>
; <34g> 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. <34g-YDS-9/2/91>
; <34f> 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.<34f-YDS-9/2/91>
; <34e> find where the click was (to define the right script).<34e-YDS-9/2/91>
; <34d> Support for a single carret, this supports the styled
; TE part.<34d-YDS-9/2/91>
; <34c> 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.<34c-YDS-9/2/91>
; <34b> using the byte after the TwoByteCharBuffer in teDispatchH for
; fixes <3.3> and <3.4> (lastScript), so change the place it clears
; so only a word will cleared there.<34b-YDS-9/2/91>
; <34a> Fixing Hebrew/Arabic AppleLink bug that causes a big cursor:
; the right way! this fix is in alot of places. <34a-YDS-9/2/91>
;
;
;
; <33> 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.
; <32> 2/14/91 SMB pke,#70628: Unfortunately, forced to remove support for Forward
; Delete that was added in <19>. Conditionalizing it out so it can
; be added again later. See <32>.
; <31> 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.
; <30> 2/14/91 SMB pke,#68221: Completing the fix in TextBox to turn off
; PreseveGlyph before drawing in order to draw squished characters
; when their ascent or descent is larger than the font's metrics.
; This problem in TextBox can be demonstrated when an accented
; character appears in a dialog. The previous fix in <22> had the
; comefrom patch on _DrawText instead of _MoveTo although the rest
; of the patch was based on the MoveTo call. So, the patch was
; never executed since the address never corresponded to a
; DrawText call! Brain damaged!
; <29> 2/14/91 SMB pke,#DTS FT: Quit trashing a4 across Hook calls!
; <28> 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.
; <27> 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.
; <26> 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.
; <25> 2/11/91 SMB pke,#SMB-2/10/91-1: TextEdit should be using the low memory
; TEDoText hook rather than jumping directly to the DoText patch!
; <24> 2/2/91 PKE KIP: Fix 606 build by renaming leftSide references in P2CFrame
; to leadingEdge in code that is only used if SysVers < $700.
; <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> 1/20/91 SMB (csd) Fix incorrect calling of FindWord and FindLine when
; patching in ReCalLines and NewRomanFindLine. Must use the
; low-memory vectors to access the patches. Added a line in
; ptchRecalLines that was accidentally dropped (thereby causing
; some linebreaking problemsÉ)
; <20> 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.)
; <19> 1/14/91 SMB (jdt) ¥ Added ptchReCalLines for a KT bug: Only draw line in
; ReCalLines when wordRedraw is <1. ¥ Fixed bug # 35646 (fixed for
; SS-6.0.4 and 6.0.5 in ptch0) - up-arrow key doesn't get to
; beginning of text. Had to add patches to PtToLine, DoFind,
; PinDisplay, PinA0Rect and the routines that called them:
; Refresh, Scroll, TEScroll, TEPinScroll. TEClick, TEKey,
; TEGetOffset, DefClikProc, DoDraw and DoHilite had to be updated
; to call these patched routines rather than the ROM routines. ¥
; Fixed bug #66732 & #57858: if the scrap handle parameter
; (newStyles) in SetStylScrap was NIL should do nothing and exit.
; (see ptchTEDispatch) ¥ Fixed bug #58512: Must lock null scrap
; handle in InsRsrved before calling PstStylGuts since PstStylGuts
; expects to use the handle again after moving memory. Since
; InsGuts calls InsRsrved, patched InsGuts and the two routines
; that call it, TEInsert & TEStylInsert. ¥ 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 Pixel2Char and
; ptchDoSearch. ¥ 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; the routines needing it (TextBox & GetSize)
; require a comeFrom tail patch on GetFontInfo. ¥ 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.
; <18> 12/15/90 SMB (gbm) Added support for another gestalt selector, gestaltTE5,
; for the new TextWidthHook.
; <17> 10/30/90 SMB (PKE) ¥ Fix text buffering bug: must preserve register a1
; (ExpandMem ptr) around a call to SetFont2Keyboard. Also, moved
; code that dumps the buffer in SetFont2Keyboard after determining
; 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.
; <16> 9/16/90 SMB Put GestaltTEciVersion proc and installation code back in.
; <15> 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
; highlight the middle rectangle line by line in order to call
; highHook for Inline. 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 (revisited:
; must also bra if equal).
; <14> 8/14/90 DTY Changed into a linked patch.
; <13> 6/22/90 SMB 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.
; <12> 6/11/90 SMB NEEDED FOR SIXPACK & 7.0: Added Inline Input bit to
; TEFeatureFlag and support for it in ClickKeyboard2Font.
; <11> 5/29/90 DDG NEEDED FOR SIXPACK: Changed all the sixpack conditionals from
; six-point-oh-seven to six-point-oh-six.
; <9> 4/27/90 SMB NEEDED for SIXPACK - Fixed old bug for old FindWord: when using an
; application's teWordBreak routine must save d1!
; <8> 4/10/90 SMB NEEDED for 6.0.x, 7.0 and SS-6.0.5: Adding Scrolling Down bug
; fix that I erroneously omitted on 1/16/90! (see comment <3>
; below)
; <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 1/23/90) for Script Systems:
; whenever backspacing over a script boundary the keyscript wasn't
; updated. Bug #59422. - Fixed TEFindWord for line breaking on a
; Roman-only system to branch for 'bge' to #teFromFind instead of
; 'bgt'. (Should have been in 1/23/90??) - 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 for 6.0.5 - DoSearch didn't work correctly when 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.
; <5> 2/13/90 SMB NEEDED for 6.0.5 - Moved conditional test in ptchDelGuts. -
; Patched TEWidthHook in GetLRPosition, PixelWidths, and GetWidth.
; Also added nTEWidthHook and OldChar2Pixel.
; - Patched TEWidthHook in GetLRPosition, PixelWidths, and GetWidth. Also
; added nTEWidthHook and OldChar2Pixel.
; <4> 1/30/90 SMB NEEDED FOR SS-6.0.4 and 6.0.5 -
; 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 -Decided NOT to fix bug 35646 for the IIci - up-arrow key doesn't get
; to beginning of text - since it wasn't very important and it would
; take a lot of patches in many routines to fix it.
; 1/29/90 smb - No longer call SetFont2Keyboard for ptchDumpBuffer.
; - 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.
; 1/23/90 - Removed all equates and records since moved them into TextEditPriv.a.
; emt - Added humane scrolling (slower) to DefClikProc (also see TEClick).
; 1/23/90 - Changed FindWord branch for linebreaking to 'bge' instead of 'bgt'.
; - 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.
; 1/8/90 SMB NEEDED FOR 6.0.4SS & 6.0.5: bug 58823, TEGetPoint returned
; incorrect values when there's no text in the TERec. ¥ 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.
; <2> 1/4/90 PKE NEEDED FOR 6.0.5 (smb's changes from SS-6.0.4b23 to SS-6.0.4f1):
; ¥ Set the offset parameter to non-zero for StyledLineBreak for
; unstyled text. ¥ In ptchTESetStyle and ptchTEGetPoint must pop
; TEDispatch's return address. ¥ Added ptchHiliteMiddle and
; patched out more of OnSameLine and MeasureWidth to use this
; patched HiliteMiddle. Have to save d2! 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 from here up:
;___________________________________________________________________________________________________
; EASE versions below:
; <1.3> 12/14/89 smb Added ROMEndDoSearch jmp address since I left it off and broke
; the 6.0.5 build!
; <1.2> 12/11/89 smb More Arabic fixes: horizontal cursor movement now works at line
; ends.
; ¥ In CursorMovement and GetStyleEnd had to pin the style run to
; the line end for correct position.
; ¥ Need to use the high caret rectangle in TEKey rather than always
; using the teSelRect!
; ¥ 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.
; ¥ Fixed LR highlighting bug at line ends; in InvrtRectangle.
; ¥ 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.
; ¥ 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.
; <1.1> 11/21/89 smb Bug fix in FindWord for Chinese Script System: clear
; fwLeadingEdge flag!
; ¥ Added updating of outlined region in TEUpdate.
; ¥ 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.
; ¥ 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!
; ¥ Fixed buffering bug in BufferChar & TEKey; must set emBufferLen
; non-zero when buffer the 1st byte of a 2-byte character.
; ¥ Moved secondStyleRun and firstStyleRun from SharedFrame to
; FmtOrderFrame since TextFrame needs this info for XTrimMeasure
; changes.
; ¥ Bug fix for buffering 2 byte text on Kanji! see DumpBuffer and
; TEBufferText.
; ¥ Removed testing of LRTextFlag since it's based on WordRedraw.
; Will tst WordRedraw instead!
; ¥ Not removing setting of LRTextFlag in GetFormatOrdering or
; teGetFormatOrder since it won't hurt.
; ¥ Had to clear (a2) in iTEFeatureFlag so that the return result was
; set right for an initial state of clear (vs. set).
; ¥ Fixed ptchTrimMeasure for unstyled TE. Also added test for
; unstyled TE in ptchGetNextDisplayStyle. Moved firstStyleRun and
; secondStyleRun to "top" of FmtOrderFrame.
; ¥ In ptchTEGetPoint changed longs back to words as they were
; originally!
; ¥ 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!
; ¥ SecondStyleRun and firstStyleRun need to be above directionParam in
; the FmtOrderFrame!
; ¥ Added @getStyleNew code for right-to-left directional scripts in
; ptchDoSearch.
; ¥ 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.
; <1.0> 10/12/89 smb New file containing the TextEdit patches from PatchIIciROM.a. Is
; included therein.
;____________________________________________________________________________
; To aid the historians, here is the recent history of TextEdit from PatchIIciROM.a:
;
; <7.7> 10/12/89 smb Moved TextEdit patches to TextEditPatchIIciROM.a. Fixed bug in
; old highlighting code that I introduced accidently (changed
; move.w -> move.l).
; <7.2> 10/5/89 smb Added old highlighting code for TextEdit for HyperCard
; outlining.
; <7.0> 10/4/89 smb Fixed 6.0.4 build by moving around some of my conditionals due
; to dependencies! Fixed TEInit to set TEDoText like it used to.
; Cleaned up TEOutlineHilite. Fixed caret display for outline
; highlighting.
; <6.8> 9/29/89 smb Added patches for TextEdit for TEFeatureFlag, SetFont2Keyboard,
; and fixed CursorMovement for double-byte characters.
; <5.5> 8/30/89 smb NEEDED FOR Scripts604 and Big Bang! Bug fix in ptchTEFindWord
; (fixed word dragging bug and now uses old FindWord code when
; RecalLines calls. Also added ptchMeasureWidth to fix a
; hilighting bug at line ends when the line direction is RL on a
; system that is normally LR (ie - Roman, Kanji, etc.)
; <4.2> 8/18/89 smb NEEDED FOR 6.0.4: Another unlocked handle problem!
; AAAARRRRRGGGGHHHHHH! (See ptchOnSameLine below)
; <3.8> 8/15/89 smb NEEDED FOR 6.0.4: Fixed some problems in my patch code for the
; bad pointer bug.
; <3.4> 8/11/89 smb smb Finally rolled in patches for a bad pointer bug (#51602) and
; an up & down arrow keys bug (#51961). See comments below.
; <3.1> 8/8/89 smb NEEDED FOR 6.0.4: Reverted TEFindWord patch since the previous
; patch introduces an uglier bug that won't be fixed now. Also
; added gestalt function for TE.
; <2.8> 8/8/89 smb NEEDED FOR 604: Added more TE patches for Aurora!
; <1.8> 7/25/89 smb NEEDED FOR 6.0.4: Added TextEdit patches for Aurora.
;____________________________________________________________________________
; To Do:
; Check insGuts: may be able to use a0 instead of a1 for _HLock.
; TEKEy: set d6 to 1,-1 and move into d3 for doublebyte call.
; Remove extraneous code from NewRomanFindLine. Marked with (XX).
; See WBOverid - could simply jump into rom again since removed ForceOldFW patch.

; PROCEDURE ptchTEFindWord
; <19July89smb> Fixed Roman FindWord hyphenation bug. Problem
; was occuring 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. The correct fix for this is
; to use the old FindWord code when the caller is RecalLines. This
; introduces an uglier bug that can't be fixed for 6.0.4 so we opted
; for the easiest fix which is to always use the old FindWord for all
; of Roman word breaking needs.
; <28Aug89smb> We now use the old FindWord code for RecalLines for
; 6.0.4 Script Systems and Big Bang since the uglier bug is now fixed.
; The bug was that the leadingEdge flag was not set correctly for word drag.
; <26Oct89smb> Bug fix for Chinese Script System: clear fwLeadingEdge flag!
; <1/17/90smb> Redone to be compatible with applications using incorrect char
; breaking algorithms for Script Systems.
; <2/28/90smb> Changed 'bgt' to 'bge' for linebreaking.
; <4/17/90smb> Fixed old bug for old FindWord: when using an
; application's teWordBreak routine must save d1!

; GetNextDisplayStyle, which is called from FindStyleRun, which
; is not vectored. So, have to fix in CursorMovement and then
; jump back into FindStyleRun.
; <28Sept89smb> Fixed double-byte bugs.
; <22Nov89smb> Had to pin the style run to the line end for
