;
; Change History (most recent first):
;
; <SM5> 5/22/93 BT Add check to see if hasDoubleByte has already been defined.
; <SM4> 11/3/92 SWC Changed INCLUDEs to a LOAD of StandardEqu.d.
; <12> 3/25/92 DTY #1023489,<FM>: <20>BLT: There is a code patch in OutlineMetrics
; which leaves the contour entry bit set in the high byte of the
; offset into the glyph data array. This causes a bus error in 32
; bit mode because this offset is used in a pointer calculation.
; Change the branch to go to existing code which clears this bit.
; <11> 9/25/91 jlf Rolled in double-byte modifications to OutlineMetrics. Always
; define hasDoubleByte.
; <10> 6/12/91 LN added #include 'SysPrivateEqu.a'
; <9> 12/11/90 CL (RB) Saving off D2 before calling sb_retrieveglyph. D2 got
; trashed and was used. Using incorrect define for descent and
; ascent. Needed to use the cache.ascent and cache.descent.
; <8> 12/4/90 CL (MR) Fixing bitmap right of bitmap. Fix YMax and YMin for
; outline style. down by one pixel. Fixing this bug.
; <7> 11/29/90 CL (RB)YMax and YMin must be initialized to eachother.
; <6> 11/12/90 CL Accouting for algorithmic styles of bold, shadow, and outline in
; the bouding box, yMax, yMin, and lsb.
; <5> 10/30/90 CL (MR)Reviewed for 7.0<EFBFBD>2
; <4> 10/23/90 CL Need to check entryOffset instead of returned error since
; sbretrieve will return an error for the clipped out case.
; <3> 10/22/90 CL (BKR) Adding support for minimum memory mode to band and run in
; low cache conditions.
; <2> 10/21/90 gbm (with dba) Get rid of bra.s warnings by re-ordering a couple of
; Procs
; <9> 10/1/90 CL Fixing some confusing comments about error handling from sbretrieveglyph.
; <8> 9/4/90 CL Memory model changed a little for the cachehandle. The cacheHandle
; could change when a sbretrieveglyph call is made since it may place
; the block in another heap. So after call is made, re-init the cachehand
; via the splinekey.
; <7> 8/2/90 gbm add an END to make assembler happy
; <6> 6/22/90 CL Added ToolEqu.a include file
; <6> 6/22/90 CL Added ToolEqu.a include file
; <5> 5/29/90 CL Spline preferred no longer needs to set Lastspextra to minusone.
; Fixed outline metrics bug when filling out widths.
; <4> 4/11/90 CL Missing characters did not decrement.
; <3> 3/20/90 CL Bug fixes to Outline Metrics and a couple of speed enhancements
; <2> 2/27/90 CL Adding Right and Left Side bearing max. Changes made for
; DrText<78>s optimizations. Re-wrote a good portion of Outline
; Metrics.
; <1.4> 11/15/89 CEL Changed functions to better names for documentation.
; <1.3> 11/14/89 CEL SetLineHeight will only invalidate the width tables instead of
; the caches.
; <1.2> 9/15/89 CEL Updated calls to be pascal conventions.
; <1.1> 8/28/89 CEL Added in IsOutline call.
; <1.0> 8/14/89 CEL Checking file in for the first time<6D> Three Additional calls
; added to Bass.
;
; To Do:
;
IF (&TYPE('hasDoubleByte') = 'UNDEFINED') THEN
hasDoubleByte EQU 1
