; Change History (most recent first):
|
|
;
|
|
; <SM3> 12/01/92 HY Defined 2 fields in CsrsDevGlobals, CrsrDevFlags and MoreCrsrDevFlags.
|
|
; Defined bit 0 of crsrDevFlags to SkipDraw. This flag indicates to skip
|
|
; drawing the cursor on the first VBL, and to only perform calculations.
|
|
; This fixes a bug which caused the cursor to flicker when it was at
|
|
; the top of the screen. (see CrsrDev.a)
|
|
; <SM2> 8/26/92 kc Roll in Horror changes.
|
|
; <H3> 7/13/92 djw <GED>Added field in CrsrDataRec which indicates how often (in
|
|
; VBL ticks) the cursor should be blitted. Added two related
|
|
; vectors in CrsrDevGlobals.
|
|
; <H2> 7/13/92 djw <GED> Added equates for two new cursor vectors.
|
|
; <SM1> 5/2/92 kc Roll in Horror. Comments follow:
|
|
; <H2> 2/17/92 SWC Changed CrsrDevRec.resolution to a long since it's a fixed point
|
|
; number, and slightly rearranged the record so everything stays
|
|
; long word aligned.
|
|
; <H1> 2/12/92 GMR first checked in
