; 03-May-85 SC Dropped forROM and for44T compile switches for readability
; 03-May-85 SC New version of FindLine, cleaner and fixes bugs. Still
; inefficient because it measures whole line repeatedly, but

; 08-May-85 SC Added default click proc for auto scrolling
; 08-May-85 SC Added TEPinScroll which does a pinned scroll (Not upward
; compatible so I couldn't include in real scroll, but it is
; used by the default click proc and TEScrollView
; 08-May-85 SC Added TEScrollView which insures selection is visible before
; doing something. Called from TEKey, TEPaste, TECut, TEIdle, etc.
; 09-May-85 SC StdEntry/Exit save restore teTextH flags
; 09-May-85 SC teLftClick not a byte, now the tefLeftClk bit in teFlags

; avoid calling _GethandleSize(done once in stdEntry)
; 13-May-85 SC Added preflight routine to check memory. Called from
; pasteguts, insertGuts, and TextBox. Did similar to TENew
; 15-May-85 SC Multiple standard entries with stack peel amount in D1. Does
; a preflight and then escapes if the preflight fails
; 18-May-85 SC Put back DoText funnel for compatibility
; 18-May-85 SC Dropped printable trim in FindLine @ end
; 18-May-85 SC LineWidth didn't handle the line past teLength correctly
; 18-May-85 SC Merged LineWidth and TrimMeasure
; 18-May-85 SC Made trim measure skip wordBreak code and only trim chars
; <= space. This should truly measure only the black characters
; And not the word break chars now. (Deja Vu - did this on 3 May
; but a bug in FindLine made it LOOK as though it didn't work
; so I undid it on 9-May)
; 18-May-85 SC New routine PinDisplay replaces pin code in Hilite and Refresh
; 18-May-85 SC Made DefClikProc obey autoScroll bit
; 20-May-85 SC DoSearch longize D3-D4 (Thanks Bill and Larry)

; 23-May-85 SC Dropped port save/restore font
; 7-Jun-85 EHB Fast TextBox shouldn't catch zero strings else no EraseRect(oops)
; 10-Jun-85 SC CharbyChar had a BLT that should've been a BLE (It gets there
; by a BGE so it should stay in loop if BLE).
; 10-Jun-85 SC DoText links a stack frame/DoBye and findDone UNLK
; 10-Jun-85 SC In rangeRect, stuff the rect.left in tempRect and set pen to
; right for compatibility with old DoText
; 10-Jun-85 SC DoSearch returns in D0 as before
; 15-Jun-85 SC Undid "teLftClick not a byte, now the tefLeftClk bit in teFlags"

; 16-July-85 SC PinDisplay has new entry point for TEUpdate compatability
; Refresh changed to take A0 pointing to an update rect not
; D0/D1, calls PinA0Rect.
; 26-Jul-85 EHB Added ShowCaret to end of TEPinScroll (needed for null scroll)
; 01-Oct-85 EHB Set up D2 for all calls to CallBreak (identifies caller)

; --------------------------------- Lonely Heifer ROMs ----------------------------
; 14-Jan-85 EHB In PasteGuts, call SelSort and get sel length for preflight
; Fix longize bug in the beginning of DoSearch
; Added cursor key support to TEKey
; <19feb86> BBM Made some modifications to work under MPW
; --------------------------------- ROM 76 ----------------------------
; <C78/17jul86> MBK removed equates to an external file; added four new
; traps (TEStylNew, iTEStylPaste, iTESetStyle, iTEGetStyle);
; 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.
; <C94/29jul86> MBK Added 3 more traps (iTEReplaceStyle, TEGetOffset, TEFindStyle);
; renamed iTEGetStyle to TEFindStyle (iTEGetStyle now returns the
; style handle); fixed selection bug, the problem was in
; ScanMeasure and DoSearch. Fixed bug in CharByChar. Started
; fixing recalibration problem.
; <C95/4aug86> MBK Fixed the scrolling problem in SelView; Modified
; Recallines to take into account changes in point size.
; <C105/3Sep86> MBK Renamed iTEGetStyle to iGetStylHandle and TEFindStyle to
; iTEGetStyle. Added iSetStylHandle. 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
; iTESetStyle and iTEReplaceStyle 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.
; <C139/10Sep86> MBK Fixed iTEGetStyle 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.
; <C182/6oct86> 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.
; <C207/16oct86>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.
; <C229/29oct86>MBK Fixed 2 register preservation problems. Fixed InsertRecal
; memory overload problem. Redesigned method of updating line heights.
; <C381/8nov86>MBK Made all changes resulting from code review.
; <C393/10nov86>MBK Fixed CopyStyle and InsertRecal to reset ptr values after a
; memory allocation call (the ptrs were pointing to trash).
; --------------------------------- ROM 77 ----------------------------
; <C440/19nov86>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.
; <C454/21nov86>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.
; <C475/02dec86>MBK Set the high bit of the pnMode before highlighting, to use the new
; background color highlighting method.
; <C485/04dec86>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).
; <C513/12dec86>MBK Changed to clear bit in HiliteMode instead of setting bit in pnMode
; for color hilighting. Fixed selection bug in Pixel2Char.
; <C574/30dec86>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.
; <C597/06jan87>MBK Restore A3 ptr after RGBForeColor call in StdExit, in case TERec gets moved.
; <C622/13jan87>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.
; ** BETA 3 **
; <C676/23jan87>MBK Added iGetStylScrap, PutStylScrap, iTEGetPoint, and iTEGetHeight.
; ** BETA 4 **
; <C717/28jan87>MBK Made changes in GetDefStyle, DoDraw, MeasureIt,
; StylMeasure, SetHiteAscent, and SetStyle to protect unlocked
; pointers from memory reallocation. Added startLine and
; endLine input to iTEGetHeight. Added RecalDraw to PutStylScrap.
; <C719/29jan87>MBK I removed the C717 change to SetHiteAscent. The ptr there
; was not an offset from styleTab, it was an addr on the stack.
; ** BETA 5 **
; <C734/30jan87>MBK I changed PutStylScrap to iTEStylInsert, 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 iTEGetHeight
; to subtract 1 from startLine because GetLineHites wants it
; 0-based. iSetStylHandle fixed to dispose of old style handle
; before setting new one.
; ** BETA 6 **
; <C766/05feb87>MBK Fixed CopyStyle to lock my style handle before calling
; PutScrap. Fixed DelGuts to relock text handle after munging.
; Removed call to StdEntry from iTEStylInsert because TEDispatch
; does it.
; <C788/11feb87>MBK Fixed iTEStylInsert to get the input parameters in the
; correct order.
; <C815/13feb87>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.
; ** BETA 8 **
; <C851/27Apr87>MBK Miscellaneous bug fixes (search on 851 to get more detailed
; descriptions); added code to handle setting styles on null
; selections.
; <C854/21may87>MBK Changed TECalText delta to 8001, fixed Pixel2Char disposhandle
; problem, fixed find style problem in PstStylScrap, fixed GetLineHites
; to work with fixed height, fixed recal deletion problem, restored input
; parameter order of iTEGetHeight.
; <C858/4jun87>MBK Fixed problems of iTEStylInsert destroying the StScrpHandle, style
; duplication problem in PstStylGuts, and iTEGetPoint returning incorrect
; offset when text ends in CR. Removed conditionals around bug fixes.
; <C905/13oct87> MSH Port to HcMac (Laguna). No color on this machine
; <C914/29Oct87> rwh Port to Modern Victorian
; ------------------------------ System 6.0 ----------------------------
; <C971/RWW101287> 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.
; <C971/RWW101987> Fixed 0 length bug in iTEStylInsert
; <C971/RWW102187> Added conditional equates to make RAM-based testing easier
; <C971/RWW102287> Patched ReCalLines to properly shrink lineStarts array
; <C971/RWW102387> Broke out some common code, trying not to reinvent the wheel:
; AnyNullStyle, GetTrueStyle, GetOneStyle
; Changed iGetStylScrap 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 iTEGetHeight to properly sort and pin start/end
; Added conditional inclusion of TEDispatch'ed routine addresses
; so I can find them without a Cray
; <C971/RWW102687> InitRsrved had some strangeness in it
; Added TESetEraseFlag and iTEContinuousStyle. Added in code to check
; for erase flag before performing _EraseRect's
; <C971/RWW102787> Changed references to faces to be byte instead of word length
; <C971/RWW102887> 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/RWW102987> Changed fail test in SetGuts to masking uninteresting bits
; Added doToggle functionality to SetGuts, StyleGuts, SetRsrved, CheckMatch
; <C971/RWW103087> Added some hysteresis to lineStarts hack, to try to prevent some
; heap thrashing from constant SetHandleSize calls
; <C971/RWW110387> 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/RWW110487> Yanked SetEraseFlag and associated logic. Only bought us about 10% - not
; enough to get excited over. Added iTECustomHook to give a high end
; way to stuff new internal dispatch table addresses
; <PMAB381/RWW020488> Took out some redundancies and moved autoscroll flag from its position in
; "teFlags" (née teRecBack) to the new dispatch record. Ooops. It acted as
; a high bit set in the new handle to the TEDispatchRec
; <PMAB387/DBG021088> Fixed bug in TEDispose where dispatch vector was not getting released for
; unstyled TE records.
; <S425/RWW031688> Fixed bug in iTEContinuousStyle and changed the way it handles face
; attributes
; <S508/RWW080288> Revisiting of S508, installed on Altair only by mistake.
; Fixes problem of TEHandle being dereferenced across a call to
; InstallIntDispatch in TEStylNew, which could thrash the heap.
; <19Feb89smb> Replaced hardware casms with feature casms, and changed routine names
; so they would not conflict with mpw includes. Also removed additional
; equates that are in ToolEqu.a.
; <28Feb89smb> Added Script Manager patch for setting up teSysJust from the system script
; for Harpo.
; <16May89smb> 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. Fix for bug 39276: changed add operation in TECustomHook
; from a long op to a word op.
; <17May89smb> Must lock the StScrpHandle for SetStylScrap to work correctly: see bug #36986.

; PROCEDURE ReCalLines
; ** Modified 6/18/86 by MBK **
; Recalibrates the line start array and sets dispStart/dispEnd to
; correct redraw spot. Starting with the selection, it figures out
; which line the selection is on. Then it recalibrates the line starts
; from there until the delta in D7 is consumed (the word wrap has
; petered out). It returns D2 and D4 to the redraw start and end.
; (It should return D3 instead of D2, but for compatibility it uses
; D2).
; Entry
; A4 points to handle
; A3 points to dereferenced TE object
; D7 contains delta in change = oldLength-newLength
; Exit
; dispStart(D2) now set to redraw start
; dispEnd(D4) set to redraw end
; Uses
; D5 for handle size (changed by setlinearray)
; ----------------------------------------------------------------------
; ** <C105/3Sep86/MBK> ** Stages 2 and 3 of Recal were totally rewritten for
; speed. I decided the insert and delete cases were
; different enough to justify handling them separately.
