; Change History (most recent first):
;
; <12> 11/5/93 IH Sync with Excelsior.
; <SM11> 10/10/93 IH Sync with Excelsior.
; <10> 9/10/93 IH Fix cursor bug in horror ROMs and SuperMario.
; <9> 8/16/93 IH #1099391 <KON>: Sync w/Reality. Fix support for apple event
; notification to procs ptrs.
; <SM8> 08-06-93 jmp Added more entries to the ROMTimingTables.
; <7> 8/4/93 IH #1101633,1098397,1101795,1101636,1102280 <KON>: Make
; DMGetROMMultiModeTable a trap (rather than a function call). Add
; private trap to begin configuring displays. Add Trap for
; animation. Temporarily set 2nd gestalt bit so Monitors CP can
; detect that calls take displayState (instead of "updateNow").
; <6> 6/22/93 IH Remove Debugger call.
; <5> 6/1/93 IH Add new calls for A1 feature complete
; <4> 5/28/93 IH #1081805,1086363: Fix App quickdraw globals to update screenBits
; bitmap (Finder uses this information to determine if an icon is
; off screen).
; <3> 4/8/93 IH Add support for mode switching.
; <2> 3/31/93 IH Clean up for SuperMario
; <1> 3/25/93 IH first checked in
; <9> 3/24/93 IH Support changing menu bar. Add RecalcMenuBar which calls
; _CalcMenuBar and if it gets a paramErr (selector not installed
; returns paramErr) then it tries to call the MBDF directly. In
; future systems When I am sure the trap is installed I can
; conditionalize the direct call to the MBDF to INITVERSION only.
; <8> 3/17/93 IH Adding patch to InitWindows to set up port. This is what
; LayerManager does to install DeskPort. What happens if
; InitWindows is called at init time? If portlist is cleared, this
; port will not get updated correctly when depths change etc.
; <7> 3/11/93 mgl Display Manager is now successfully installing its Gestalt
; selectors again, so I will reenable the call to SysError that I
; commented out earlier.
; <6> 3/10/93 JDR After checking in my fix <4> it occurred to me that the Gestalt
; proc should have been an LeaResident.
; <5> 3/10/93 mgl Gestalt was failing because the Gestalt proc was not in the
; System heap. Comment out the call to SysError until this is
; fixed.
; <4> 3/9/93 JDR Fixed the system build. Moved DMGestaltProc being imported to be
; outside of the for INITVERSION conditional.
; <3> 3/5/93 IH Add desk patches and gestalt procs
; <2> 2/25/93 IH Added new desktop routine dispatchers and added routine to draw
; desktop the old way.
; <1> 2/23/93 IH first checked in
