;
; Change History (most recent first):
;
; <SM4> 12/7/92 CSS Update from Reality:
; <64> 12/4/92 KSM Don't call DisposHandle if NIL upon exiting even though the call
; can handle it. It wastes time and inhibits debugging other
; things.
; <SM3> 11/5/92 SWC Changed PackMacs.a->Packages.a.
; <SM2> 10/16/92 RB Removed SOME of the NOT forROM conditionals, since some of that
; code did not make sense anymore for SuperMario ROMs. This fixed
; the disabled menu items not being drawn in gray color instead of
; gray pattern.
; <63> 8/22/91 KSM csd,#Bruges: fix font/face cleanup problem in script systems.
; <62> 3/26/91 KSM rlc,#85632: Reset the font back to the default after script
; changed it.
; <61> 3/22/91 KSM dty,#83819: Reroll change <55> per Gang Of 5.
; <60> 3/22/91 DTY bbm, #oops: Change <59> started plotting the label colours and
; other small icons in a 32x32 grid because a beq was entered as a
; bra. Change that branch to the way it should be.
; <59> 3/20/91 KSM dcc,#82082: Fix bug where cicn rect size is used to plot
; nomarksmallicons.
; <58> 3/15/91 DTY gbm, #83819: Unroll <55> because Go5 said don<6F>t fix.
; <57> 3/4/91 dba dty: kill SysVers conditionals
; <56> 2/27/91 KSM ngk,#ngk-b5-001: Fix #51 (BRC#80417) uncovered a fudge in the
; DoCalcItemMsg msg which is no longer correct (ADDQ #4,d7) and
; was removed.
; <55> 2/27/91 KSM rlc,#83819: Call RemoveBalloon before scrolling to avoid wrong
; balloon bits being restored.
; <54> 2/25/91 KSM dcc,#DCC003: Don<6F>t use ttDisabled mode to plot icons in B&W mode
; when the item is disabled. Painting gray over that icon might
; completely erase it.
; <53> 2/20/91 KSM stb,#1003794: Don't call ProcessMgr unless trap is implemented
; (i.e., at boot time).
; <52> 2/11/91 KSM NGK,#None: Fix non-7.0 build problem.
; <51> 2/10/91 KSM RLC,#79297: Speed up CalcMenuSize by calling GetItemRecord in a
; loop! This avoids calling ExpandItem each time. Each time
; through the drawing loop, TextFace and TextMode were being
; called. The strategy has been changed to now set up the
; environment outside the loop, then change it only when necessary
; and change it back before the next iteration. 22% speed up.
; RLC,#80417: A branch in calc size routine never added the
; padding to the item width for items w/ small icons or h-menus.
; RLC,#80417: Also (from same bug report) we find that the calc
; for h-menus of id=256 never got the space for the arrow added to
; them NGK,#82082: NEVER try to plot a CICN when it<69>s a
; NoMarkSmallIcon
; <50> 1/14/91 KSM <kaz> Clean up and speed up GetItemHeight (round 2).
; <49> 1/13/91 KSM <KAZ> Update register saving conventions for GetItemHeight (No
; longer saves D4 and D5).
; <48> 12/12/90 KSM <dba> Fix for disabled items: use new icon utility calls to plot
; all icons in "true gray" , and draw h-menu arrow in true gray.
; Also fix cicn centering bug when icon is smaller than text (Finder Label menu).
; Alex you saved TOO MANY registers in GetItemHeight, routines depend on D7 being set up!
; <47> 11/29/90 RLC <ksm> Move the tip of the balloon 8 pixels inside the menu
; item's rect. (The help manager used to do this instead of having
; the MDEF do it. This meant that all custom MDEF's would have
; their tips be 8 pixels off horizontally).
; <46> 11/19/90 kaz GetItemHeight now looks at the text face to return the height
; (as outline & shadow are taller than plain). DrawMenu loop uses
; GetItemHeight instead of MFHeight. <jng>
; <45> 11/12/90 kaz Broke out GetItemWidth() as a utility from CalcMenu() <20>
; CalcMenuItem() will now return the individual item size instead
; of menuWidth. <KSM>
; <44> 11/9/90 RLC <ksm> Remove check of menu title bit in MenuEnable flags when
; passing itemHelpString to the __HMShowMenuBalloon call.
; <43> 11/2/90 KSM <ngk>TextMode 31 was left on after a drawItemMsg.
; <42> 10/29/90 kaz drawItemMsg now draws the background in color; Color calls no
; longer RTS for popup CDEF. <jng>
; <41> 10/16/90 RLC When calling HMShowMenuBalloon, don't pass itemHelpString in
; itemReserved parameter if entire menu is disabled (probably by
; modal dialog menu being up). Otherwise, the help manager puts up
; the Aux menu information when, in fact, the menu item and title
; should have gotten the 'modal dialog menu' help message.
; <40> 10/10/90 KSM Fix bug where we couldn<64>t draw more than 256 items (real
; important).
; <39> 9/28/90 KSM <dba> Fix bug where no icon is drawn for items that have
; hierarchical menus (instead, we draw only a large icon).
; <38> 9/16/90 RLC (KSM also) Change call to HMShowMenuBalloon to pass the
; helpstring StringHandle (in itemReserved parameter longword)
; found in AppleMenu & System Menus after calling _GetAuxMenuItem.
; Make sure all fields of AuxMenuItem Record are clear b4 calling
; _GetAuxMenuItem.
; <37> 9/15/90 KSM Consolidate the blitting arrows code. Save 126 bytes.
; <36> 9/11/90 KSM Remove some unnecessary register saving in DoCalcItemMsg and
; DoDrawItemMsg. Update DoCalcItemMsg to call _CalcMenuSize and
; GetSizes to set up stack frame correctly.
; <35> 9/11/90 gbm make PixPats be allocated in the system heap, since they need to
; stay around in the color window manager port when apps go away
; <34> 9/7/90 KSM Add enabledState to stackframe to factor out multiple calls to
; EnableTest. Fix auxmenuitem stack frame to be in sych with
; MFPrivate.a. Intense speed up of GetItemRecord by caching some
; data in locals.
; <33> 8/24/90 BG Conditionalized System 7.0 feature so that it doesn't interfere
; with building ROMs.
; <32> 8/21/90 RLC Remove all of that extraneous LastStrAttrPtr junk and make the
; calls to mChooseMsg not always call HMRemoveBalloon() [FASTER!].
; <31> 8/17/90 dvb More grayish problem
; <30> 8/17/90 dvb grayishTextCopy->grayishTextOr
; <29> 8/15/90 BG In DRAWITEXT, there was a check after the item had been drawn to
; see whether one is onColorMachine and to not gray the item out
; if -onColorMachine- is true. This is not correct and the check
; was removed. There was a comment indicating what the code was
; originally supposed to do that had been removed and that comment
; was restored as well. If there _is_ some problem with trying to
; gray out menu items on color machines, it SHOULDNT be fixed by
; just not graying out the item. Have a nice day.
; <28> 8/13/90 JSM Fix previous fix.
; <27> 8/10/90 PN Fix graying for non-color machines since drawstring on these
; machines does not recognize _PenPat(grayishtext).
; <26> 8/9/90 DC Fixed up color environment again to look even better (I hope)
; <25> 8/6/90 DC Fix up color environment around PlotIconSuite for menu
; colorizers (Kolor et al.)
; <24> 8/6/90 RLC Change _Button to _Stilldown to fix multiple calls to mChoose
; message redrawing balloon.
; <23> 8/2/90 kaz TruncateString() now saves D1 (sys just). Fixes a bug with
; DrawItem w/ sysJust == right.
; <22> 7/20/90 DVB Fix for b&w systems
; <21> 7/17/90 DVB Enable grayish menu items
; <20> 6/12/90 PKE NEEDED FOR SIXPACK: Fixed bug in default setting of itemScript.
; <19> 6/11/90 kaz Removed condensing for drawItemMsg per HI request.
; <18> 6/4/90 kaz Fixed a bug where DoCalcItemMsg tried to get the menuWidth off
; the menu handle rather than the menu ptr.
; <17> 5/31/90 DC Changed the name of selected transform constant from
; ttPrimitiveSelected to ttSelected (Sorry)
; <16> 5/30/90 DC Changed name of icon interface from IconUtils.a to Icons.a
; <15> 5/23/90 ngk Icon ID for StandardFile will now use an offset from -4000
; rather than 256. <KSM>
; <14> 5/22/90 DC Changed name of PlotBestIcon to PlotIconSuite
; <13> 4/25/90 DFH Fix "gray" icon plotting to use ttOffline rather than
; ttDisabled. Looks way better.
; <12> 4/23/90 RLC Remove help mgr macros and include the Balloons.a file instead.
; <11> 4/11/90 RLC Fix quik typo in ttSelected, (SP)
; <10> 4/11/90 KSM Update calls to _GetAuxMenuItem to include itemnum param and add
; support for color icons.
; <10> 4/11/90 KSM Update calls to _GetAuxMenuItem to include itemnum param and add
; support for color icons.
; <9> 3/19/90 EMT Removed unneccessary ROM85 test.
; <8> 3/14/90 JSM Fix bug calculating width for menu items with sub-menus, also
; was adding 1 pixel indent for NoMarkSmallIconCmd items width
; calculations to wrong register.
; <7> 3/8/90 HJR Remove extra IF hasPopupCDEF statement so that file will
; assemble.
; <6> 3/8/90 BBH fix check for mDrawItemMsg in truncatestring (screwed up the
; comparison). sorry
; <5> 3/8/90 BBH use TruncString instead of my braindead routine. Also, we check
; to see if the MDEF message is mDrawItemMsg (which is the only
; case we will want to truncate) to eliminate the truncation check
; for regular mDrawMsg's.
; <4> 3/5/90 BBH added popup cdef support to mdef
; <3> 1/31/90 JSM Add NoMarkSmallIconCmd itemCmd for Standard File.
; <2> 1/23/90 RLC Update BalloonHelp macros.
; <2.4> 11/17/89 dba got rid of checks for 64K ROMs; tightened up 7.0-specific parts
; <2.3> 9/26/89 CCH added conditionals around references to SysVers equate for ROM.

; Version 13.
; <2.1> 9/12/89 RLC fix Balloon Positioner for menus.

; HMShowMenuBalloon call
; <1.8> 8/22/89 SES removed references to nFiles.
; <1.7> 8/21/89 PKE NEEDED FOR 6.0.4: (really dba) Fix bug in bug fix. GrayRect
; takes its parameter in A0, so A0 must be set up with TempRect
; before calling GrayRect. I tried to fix the earlier bug by not
; relying on A0 -- big mistake. Instead, get TempRect into a0.
; <1.6> 8/15/89 dba NEEDED FOR 6.0.4: fix bug in GetItemHeight where it relies on
; GetIconSize not trashing A0
; <1.5> 8/10/89 RLC Changed selector message to Help Mgr Pack to MOVEQ #select,D0
; <1.4> 6/2/89 KSM Updated conditionals for ROM/SYS build AGAIN.

; Msg #3 -- Calc TopMenuItem and MenuRect so that the top of PopUpItem is at TopLeft
;
;----------------------------------------------------------------------------------------
; Begin by calculating how far the top of WhichItem is from the top of the menu.
; Then place the menu. The various possibilities are:
; 1. The whole menu fits on the screen and PopUpItem lines up with TopLeft
; 2. The whole menu fits on the screen and PopUpItem cannot line up with TopLeft without
; causing the menu to scroll. In this case adjust menuRect so that complete menu is
; is on the screen, but PopUpItem is as close to TopLeft as possible.
; 3. The whole menu is not on the screen. In this case adjust the menuRect so that as much
; of the menu is showing as possible on the screen, and position PopUpItem so that
; it is showing and as close as possible to TopLeft.
;
; Return the MenuRect and TopMenuItem. TopMenuItem is returned in the VAR PopUpItem param.;
;
; Historical Note: It would be desireable to have popups change vertical size as they scrolled,
; instead of having all that white space when the scrolling menu is first
; displayed. The reason for this is due to the design of the MBDF.
; The MBDF saves the bits behind and draws the drop shadow at the same
; time. If there were two messages instead, one to save the bits behind
; and one to draw the drop shadow, the we could save all of the bits behind
; the menurect, from the top of the screen to the bottom, and then change
; the menu<6E>s vertical height without worrying about saving more bits each
; time it got bigger. But we can<61>t, so...
