; Change History (most recent first):
;
; <9> 7/1/92 JSM Fix bug in one of the changes I made for TheFuture in the last
; revision, add comments about IIci patches that have been rolled
; into ControlMgr.a: FixNewControl32Bit,
; PatchDisposeControlForInvisibleControlsIIci,
; PatchDisposeControlForCorrectLayer, CheckMemErrInSetCTitle, and
; ThrottleScrollingSpeed.
; <8> 6/30/92 JSM Move patch on _TrackControl for scroll speed throttling here
; from ScrollSpeedFix.a, add a MakeInstall for TheFuture to
; allocate globals in ExpandMem for this patch.
; <7> 4/22/92 pvh Fix bug so that the right layer is switched in when we're
; disposing of a control (_DisposeControl patch). Added new patch
; to swap in the correct layer before calling real
; _DisposeControl.
; <6> 1/18/91 VL <jsm> DrawThumbOutline should check whether it is coming from
; DragControl also. Otherwise, we may be accessing bogus
; ControlRecord.
; <5> 1/13/91 VL <dba> Added a patch to FrameRect to draw a solid outline when
; dragging the thumb in 7.0 scroll bar (CDEF 1).
; <4> 11/8/90 dba & gbm; move patch that does a system error if we cant load a
; CDEF here from PTCH files; move patch that disables Plus check
; for control visible (for MacExpress) here from PatchPlusROM
; <3> 10/24/90 KSM <dba>Fix SetCTitle to check if SetHandleSize failed.
; <2> 10/8/90 dba move the NewControl/contrlOwner bug fix here from
; WindowMgrPatches.a
; <1> 9/23/90 dba Created today with two patches; NewControl heap scramble bug in
; 32-bit mode, DisposeControl erasing invisible controls.
