Changes for 42.2
- graphics/BitmapScale() did not work properly for 24bit 3BPP CyberGraphX
maps (e.g. corrupt graphics with Voyager 2.x/3.x on 24bit packed pixel
screens)
- added additional parameter clipping to graphics/GetRGB32() patch to
avoid memory trashing problems when invalid parameters were used for
the starting colour or the colour count
- added an additional WaitBlit() after chip->chip bitblits to avoid problems
with slow amiga blitter
- fixed a "crawling ants" problem in the line drawing code if someone tried
to draw a patterned line with only one pixel length
- For doublescan screens the vertical mouse resolution is halfed which should
half vertical mouse speed, too
- A datatypes.library >= v44 is not patched by CyberGraphX anymore
- CyberGraphX's OpenScreenTagList() patch now passes the SA_Pens tag
to intuition even if a workbench type screen is to be opened. This
fixes the problem that ScalOs assigned system pens were ignored before.
- fixed a bug in graphics/BltMaskBitMapRastPort() patch which caused this
function not to work properly when the source bitmap was relocated to
graphics board video memory. This should fix the transparent NewIcons
rendering bug in conjunction with the BITMAPCACHE option in Scalos.
- BltBitmap[RastPort]() & ClipBlit() with minterm 0x6x (src EOR dst) now really
do a src EOR dst operation instead of swapping src and dst bits on extended
chunky maps. This fixes some problems with Iconian's popup gadgets on
high/truecolour screens for example
- added new environment variable FORCECHUNKY to disable/enable
graphics/AllocBitmap() BMF_MINPLANES flag compatibility kludge (was required
by applications like old picture/animation.datatype which relied on
AllocBitmap() returning planar bitmaps even when a friend bitmap was passed).
This switch defaults to off.
Changes for 42.1
- cybergraphics vblank interrupt handler is now only installed if at least
one graphics card is configured for draggable screens
- fixed some problems with doublebuffered screen bitmaps
Changes for 42.0
- initial v4 release
