; 25-Jan-85	EHB	Added Capp's TextBox fix
; 16-Jan-85	EHB	Fixed center/right justify in TextBox fix
; 03-May-85	SC	Fixed the <CR>-in-1st-char bug with word select.  FindWord
; 					would abort if the left char scan got to the beginning, but
; 					it wouldn't check if the 0th char was a break character or not
; 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
; 					faster quickdraw fixes this.
; 03-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.
; 04-May-85	SC	Changed D2 usage in TEClick to D5 long sign bit
; 04-May-85	SC	SkipLoop in TrimMeasure could go negative
; 04-May-85	SC	Dropped DelGuts and InsGuts call from PasteGuts and made a
; 					combined inline call for munger speed.  Could make DelGuts and
; 					InsGuts inline since only 1 caller, but left that for another day
; 05-May-85	SC	Made StdEntry/Exit use LINK instructions not SP based
; 05-May-85	SC	TESetSelect trashed teSelPoint, cleaned up code a bit

; 06-May-85	SC	DoText used tempRect, use stack frame instead
; 07-May-85	SC	Undo refresh hilite stuff, moved similar stuff to Hilite
; 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

; 09-May-85	SC	Made a local CalText proc to avoid StdEntry
; 11-May-85	SC	Completely trashed DoText, OffsetStuff, DoFormat and
; 					replaced them with a clean versions of DoFind, DoHilite,

; 					problem, the direct pen adjustment and general mayhem
; 					With the old DoText.
; 11-May-85	SC	Local proc Scroll broken out for use by TEScroll and TEPinScroll
; 11-May-85	SC	Reinstated teSelPoint, it's in documentation

; 12-May-85	SC	Use D5 in recallines to hold telength
; 13-May-85	SC	Save/Restore text stuff in std entry/exit and made setlinarray
; 					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)
; 20-May-85	SC	CleanupSel saved teTextH flags twice!!
; 20-May-85	SC	Fast TextBox didn't catch zero string length case (oops)
; 20-May-85	SC	SelView called before caret view in DelGuts and PasteGuts;
; 					should be after (leaves carets behind in Dialogs)
; 21-May-85	SC	Added negative length to Fast TextBox
; 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"
; 					had to drop back to old one for compatibility.  TERecback is
; 					now the TEFlags
; 15-Jun-85	SC	DoText must return ThePort in A0 for compatibility
; 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)

; 03-Nov-85	SC	Fixed special case D3=0 in DoCaret
; 05-Nov-85	EHB	Moved label to make WordRedraw fix work right

; --------------------------------- 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.

; 			of a change in line height (and the offset must be the same as
; 			a line start if the line height has changed); otherwise, I
; 			don't erase the previous character since it's going to be

; 			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

; 			** <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 iTESetStyle.  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 iTEGetStyle, 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.

; 	<C971/RWW102687>

; 					the selection, doFace is returned TRUE if it was requested.
; 					Seems this is a more required case than the original allowed for,
; 					(and besides, it is a helluva lot easier case to code for)
