- 2.1a Release - August, 1994. SVGAPV21a (registered version only)
- Bugs Fixed: DRWFILLCIRCLE,DRWFILLELLIPSE - When using the 'XOR' mode,
- some lines were drawn twice resulting in a 'sun set'
- effect.
- DRWLINE - using the 'AND' mode on a horizontal line
- resulted in the first few pixels (left most) actually
- being drawn in the 'SET' mode; this bug also affected
- the following functions (only when using the 'AND'
- mode): DRWFILLBOX, DRWFILLCIRCLE, DRWFILLELLIPSE,
- FILLCONVEXPOLY, FILLVIEW.
- Registered disks did not include the 'EDTMOUSE.TXT' and
- 'EDTFONT.TXT' as stated in the file 'PACKING.LST'.
- These files were however included in the main
- documentation files.
- Improved: DRWFILLCIRCLE - speed increase of about 16%
- DRWFILLELLIPSE - speed increase of about 30%

- Bugs Fixed: FILLAREA - not always making it to left edge when left edge
- was the viewport and not the border color.
- FILLCOLOR - not always making it to left edge when left
- edge was the viewport and not the border color.
- GIFMAKE - under certain circumstances would produce a
- corrupt GIF file.
