|
|
;
|
|
; <SM3> 11/3/92 SWC Replaced INCLUDEs with a LOAD of StandardEqu.d.
|
|
; <SM2> 6/09/92 CSS Roll-in changes from Reality:
|
|
; <16> 5/12/92 DTY kFontsFolderType is defined in FoldersEqu.a now.
|
|
; <15> 5/8/92 DTY #1029162: The interface for OpenResFileUnderSystemMap
|
|
; has changed. Pass in fsCurPerm to the call now for the
|
|
; permission to open the font files with.
|
|
; <14> 5/8/92 DTY #1029253: After opening the fonts, expand the FCB array by the
|
|
; number of fonts opened.
|
|
; <1> 4/16/92 PN first checked in
|
|
; <13> 1/30/92 DTY Change maxFontFiles to 128.
|
|
; <12> 1/22/92 DTY For each font file thatÕs opened, call _ResolveIDConflicts to
|
|
; make sure there are no duplicating resource IDs.
|
|
; <11> 12/6/91 DTY Remove the code that opens font files, and call _AddSuitcase
|
|
; instead.
|
|
; <10> 11/11/91 DTY The code was actually stopping after it looked at 50 files, not
|
|
; after opening 50 files.
|
|
; <9> 11/5/91 DTY Take out the code inserts a font resource map in the resource
|
|
; chain, and call _InsertFontMap instead.
|
|
; <8> 11/2/91 DTY Take out the one deep patches now that the resource override
|
|
; stuff takes care of it all.
|
|
; <7> 10/18/91 DTY kCreateFolder is a byte value, not a word value.
|
|
; <6> 10/16/91 DTY Set the dontCountOrIndexDuplicatesBit and the twoDeepBit on the
|
|
; resource maps of the font files that are opened.
|
|
; <5> 10/14/91 DTY Remove _RealFont patch since all the work is now done inline
|
|
; inside the Font Manager.
|
|
; <4> 10/4/91 DTY Add patches to one deep resource calls (_Get1Resource,
|
|
; _Count1Resources, _Get1IxResource, Get1NamedResource, and
|
|
; _Unique1ID) to do n-deep resource calls when looking for a font
|
|
; resource in the System file.
|
|
; <3> 9/30/91 DTY Make the current zone the system zone so that all resource maps
|
|
; load into the system heap.
|
|
; <2> 9/23/91 DTY Set the sysHeap bit for every resource in the map. Also add a
|
|
; limit of 50 files to open.
