;
; Change History (most recent first):
;
; <SM40> 9/30/93 IH Change hasDisplayMgr feature to hasDisplayMgrWindows. This
; allows me to build the display manager in the gibbly without
; patching out the window manager on PDM.
; <SM39> 9/9/93 SAM w/jdr Saved D1 thru a call to CopyRgn in DragTheRgn. Bad Ernie.
; <SM38> 9/2/93 SKH The gray region was not being set up correctly for non-rounded GDevices
; <SM37> 6/22/93 kc Check window title handle before dereferencing it in GetWTitle.
; <SM36> 6/17/93 KW (LW11 fau) In the dragThumb routine, check to see if the
; emControlHandle is nil, and if so, do the normal case where we
; use Paintrgn. (LW10 fau) Cleaned up the use of DragFlag to
; always set and test a word.
; <SM34> 6/14/93 kc Roll in Ludwig.
; <LW6> 5/3/93 chp Flush the caches for WDEF handles smaller than 32 bytes. It used
; to be 16 bytes, but a 22-byte, unflushed, fake defproc has been
; discovered in Software Ventures Microphone II and Microphone
; Pro. (RADAR #1082386)
; <LW4> 3/8/93 fau In the CallWindow routine, flushed the cache if the WDEF handle
; is less or equal to 16 bytes. In previous ROMS, HLock was doing
; the cache flush, but SM Roms don't do that anymore. See the
; comment for more details.
; <SM34> 6/7/93 CSS Per Shannon Holland, fix another problem if the scroll bar was
; unable to get the colors it needed to draw the shaded colors on
; color monitor.
; <SM33> 6/3/93 CSS Per Shannon Holland and KON, change the pattern to black when we
; do our special thumb dragging routine. This fixes a bug in PDM.
; <SM32> 5/17/93 CSS Per code review with Mark Law and Kevin Williams of Cyclone:
; change test for whether we changed ports to WMgrCPort from a
; test of PortOffset (the failure case would be if local 0,0 is
; ever equal to global 0,0 which is possible even though unlikely)
; to testing if the port is color again.
; <SM31> 5/5/93 CSS Make sure that the clip is wide open when we use the wmgrcport
; when dragging the thumb.
; <SM30> 5/5/93 CSS Dean fixed a problem with <SM29> not working properly when
; drawing in black&white ports. Also, I cleaned up some of the
; code.
; <SM29> 4/30/93 CSS Make _DragTheRgn drag a black box when we are dragging a scroll
; bar thumb. We tell this by using the DragFlag. So, we must be
; careful about clearing this flag after we are done with it. The
; clear state (DragFlag=0) is the original behavior of _DragTheRgn
; <SM28> 4/8/93 IH Touch file to force rebuild because default state of
; hasDisplayMgr flag is changing for RISC builds. Display Manager
; will not initialize properly without recompiling this file.
; <SM27> 3/31/93 IH Use Display Manager to Draw Desktop if hasDisplayMgr is true.
; <SM26> 2/4/93 CSS Rollin Horror (WindowMgrPatch.a). Comments follow:
; <H5> 7/8/92 SWC Fixed a bug in InitWindowFramePatch that would cause it to fall
; thru to the ÔnormalÕ code even in the LCD case.
; <H4> 01/27/92 jmp Removed the BoxFlag dependencies in these patches, and padded to
; match the TERROR/Zydeco ROM map.
; <H3> 1/14/92 SWC Added DB-Lite LC to the list of LCD screen machines. Changed
; boxTIM and boxTIMLC to boxPowerBook170 and boxPowerBook140.
; <H2> 10/29/91 jmp Did a quick-and-dirty update to the InitWindowsFrame and
; InitWindowsRgn patches to support DB-Lites. These routines need
; to be cleaned up soon.
; <SM25> 1/13/93 kc Change BSR's to JSR's to appease the Linker gods.
; <SM24> 12/10/92 HI Modified CallWindow to save the A4 register for those WDEF's
; which trash it (specifically Dreams 1.1). (Hoon Im)
; <SM23> 12/09/92 HI Modified DragTheRgn to set/clear the emIsDragging field of
; ExpandMem upon entry/exit. This allows OSEventAvail to determine
; whether to execute the HelpMgr patch code or bypass it. The
; HelpMgr patch code causes the HelpMgr to remove/show balloons
; which trash the clipRgn, penPat, and penMode of WMgrPort; then,
; DragTheRgn canNOT properly remove the drag region. Bypassing the
; HelpMgr patch code solves this problem and IT IS supposed to
; behave this way in the first place. (Hoon Im)
; <SM22> 11/3/92 SWC Changed PaletteEqu.a->Palettes.a.
; <SM21> 9/17/92 kc Remove short branches.
; <SM20> 7/15/92 PN Fix the bug in ShowHide where the show/hide flag was push on the
; stack before jsr Preshowhide. The byte gets pushed was not the
; flag but some garbage since the offset from (sp) was wrong.
; <SM19> 7/13/92 FM Fixed a bug in send behind. In the case where a window had
; actually been moved forward by SendBehind I wasn't preserving
; the original nextWindow in a4. As a result the loop was
; comparing to whatever garbage happened to be in a4 which would
; often cause a crash. Basically just a dumb mistake on my partÉ
; <SM18> 6/22/92 RB Rolled-in the Help Manager patch to ShowHide from
; BalloonPthc28.a, HMShowHidePatch.
; <SM17> 6/12/92 CSS Roll-in Reality Changes:
; <10> 6/11/92 FM Removed the obsolete call to FixSMgrWorld.
; <SM16> 5/22/92 FM
; <SM16 > 5/5/92 FM Redo the windowmgr patches and bring up to date w/ Reality:
;
; deleted calcviswindow since it is completely patched out. Kept SubStructLoop.
; deleted CheckUpdate because it is completely patched out
; and PaintBehind
;
;
; rolled in patchSectRgn. Just needed to call _ClipAbove instead of JSRing
;
; rolled in CheckPaintWhiteWord. Changed a tst.b to a tst.w
;
; rolled in PaintDesk from WindowMgrPatches.a into PaintTheDesk in the WindowMgr.a file.
; I renamed the routine PaintDesk (as in the patch file) and I took out the ROM85 check for
; color since the SuperMario ROM always has color. Took out export of NoDeskHook. Its no
; longer needed since (yet again) we're not jumping through the patch file anymore.
;
; rolled in PreShowHide more cleanly in ShowHide.
;
; Renamed InitWindows as InitWindowsGuts so that we wouldn't be bouncing between the patch
; file, LayerMgr.c and here. The Dispatch Table now points to __InitLayers
;
; copied over Philips NewWindow and NewCWindow routines and broke them into procs.
;
; Renamed closewindow as closewindowguts so that it can be called from the layermgr
; and the dispatch table won't point at the patch file.
;
; rolled in patch to move ShowHide call in closewindow, in front of KillControls to eliminate unecessary redrawing
;
; Changed all frontwindow calls to JSR __ActiveWindow
;
; Rolled in ShowHideInShowWindow correctly (and cleaner). Otherwise we would be trashing A1 all the time.
;
;
; Roll in SetWTitleActivatePalette
;
; Rolled in PaintOneInMoveWindow w/ explanation.
;
; Cleaned up the ugly patchFrontWindow selectWindow case
;
; re-roll in the SendBehind patch instead of copyingy and pasting it so it is easier to read
; and more straightforaward.
;
; fixed bugs due to copy and paste in the BeginUpdate and EndUpdate
; proceudres.
;
; Rolled in PatchDragGrayRgn
;
; Renamed FindWindow as findlayer because thats what the patches did. Saves us going through
; the patch file.
;
; ReRolled in the fixes to SetCtlColor and SetWinColor which were messy and wrong.
; Added utility routine GetRearWindow
;
;
; <9> 4/23/92 DTY The last change leaves a region on the screen if you drag a
; window over the menu bar, then back again. If the outline is
; just becoming visible again, donÕt do the XorRgn.
; <8> 4/21/92 DTY Get rid of the Òfast paintÓ case in DragTheRgn. _PaintRgn is
; fast enough now to deal with funky regions. Also reworked
; dragging algorithm so the region doesnÕt flicker as it is
; dragged around.
; <7> 4/17/92 DTY Dean hates the fact that everythingÕs lumped into one huge Proc.
; Make separate procs for all the routines.
; <6> 9/25/91 JSM Also, stop using useless conditional HMenus.
; <5> 9/25/91 JSM Cleanup header, remove use of hasCQD from this file since all
; future ROMs will have color QuickDraw.
; <4> 9/13/90 BG Removed <3>. 040s are behaving more reliably now.
; <3> 7/19/90 BG Added EclipseNOPs for flakey 040s.
; <2> 1/18/90 DVB Include PalettePriv.a
; <1.5> 12/4/89 MSH Moved a local label into a conditional.
; <1.4> 10/31/89 dba concatenated source files WindowMgr1.a, WindowMgr2.a and
; WindowMgr3.a to this one
;
; Note: This file used to be split into four pieces. Here are the modification histories for each:

; Post Lonely Hearts Changes
;
; <C59/30Jun86> DAF Changed InitWindows to allocate window and control Aux
; structures and desk colors
; <C75/15Jul86> DAF Updated default colors to work w/new QD
; <C106/5Aug86> EHB Make sure we use the right BOUNDS for color ports
; (only needed for nuMac, but works for old)
; Added NewCWindow.
; <C168/17Sep86> DAF Added InitMenus to InitWindows so that menuBar def
; proc is initialized before attempting to clear
; the bar region. THIS NEEDS A BETTER RESOLUTION!
; <C203/08Oct86> DAF updated wmgr to RGBColor. Revamped InitWindows.
; <C388/09Nov86> DAF reverted to setting wmgrPort rather than wmgrCPort for
; compatibility
; <C424/18Nov86> DAF converted InitWindows to use look in system file, then ROMresources
; for default window and control colors (wctb=0,cctb=0). Added
; DeskCPat init stuff in InitWindows. Also made some 32-bit changes.
; <C491/08Dec86> DAF general cleanup from code review. Added GetWVariant.
; Restructured desk pattern stuff in InitWindows.
; <C589/03Jan87> EHB Added SmartMove routine for multiple screens
; <C591/04Jan87> DAF Improved 32-bit handling. When MMUFlag=1, moved variant code to
; auxWinRec
; <C612/11Jan87> DAF set visible flag in off at beginning of NewWindow, so
; SetWinColor doesn't try to draw with invalid portRect in 32-bit.
; <C666/21Jan87> DAF Fixed LoadResource in CallWindow. Switched to using pRAM copy
; bit (pCDeskPat) to tell which deskPat to use. Switched to using
; rGetResource when loading wctb,cctb in InitWindows. Switched 32-bit
; stuff to use MMU32Bit (the correct flag)
; <C725/31Jan87> DAF Adjusted InitWindows to read binary deskpat always. Also does not
; look in ROM for ppat=16.
; <C768/06Feb87> EHB Make sure that each device is active in InitWindows.

; This is better since Juggler can gracefully terminate this app.
;
;------ Aurora -------------------------------------------------------------
;
; <1.3> DAF Improved DeskCPat handling in InitWindows
; <1.4> DAF Updated CloseWindow to correctly handle the auxWinRecs in 32-bit addressing
; mode. Also, dvb had an update to the Palette disposal routines.
; <1.5> DAF Moved clearing of WWExist to end of InitWindows (when it's really done!)
; rather than at beginning. This helps out the Palette manager when it's
; dealing with the color apple in the menubar during InitWindows' InitMenus call.
; <1.6> DAF Fixed an old bug for Ernie. TrackGoAway passes a word-sized part code to the
; WDEF in a long-size field. Make sure that the hiword of the long is clear.
