Short:        CyberGraphX Extension Update
Author:       fmariak@chaosengine.ping.de,marvin@sun.ph-cip.uni-koeln.de

Type:         driver/video
Architecture: m68k-amigaos


The CyberGraphX system was designed to define an independant graphics
standard for graphics boards. We also wanted to continue our development
of graphics extensions. We could include all our knowledge of about 3 years
of gfx board software development (graphics extensions for Visiona, Domino,
Picasso II and now the CyberVision64).

CyberGraphX is based on hardware dependant monitor drivers and hardware
independant libraries. This has some advantages: Bug fixes in the graphics
extension or speed optimizations is of benefit for ALL gfx boards that are
supported by the CyberGraphX system.

CyberGraphX allows using of 15/16/24 screens independant of the used
color model. You are able to use the cybergraphics.library functions to
modify this screens.

Currently there are versions for:  CyberVision64/3D

CHANGES:

 cybergraphics Revision 40.111
 ------------------------------
   - graphics/BitMapScale() now also supports scaling of chunky,hicolour and
     truecolour bitmaps. It only worked for planar destinations before.

 cybergraphics Revision 40.108
 ------------------------------
   - gained some speed when allocating true colour bitmaps with
     graphics/AllocBitMap() that don't need to be cleared. This may improve
     window refresh performance sligtly for large windows.

 cybergraphics Revision 40.107
 ------------------------------
   - flood fills are a bit faster for planar bitmaps now. This should improve
     performance for certain flood fill operations on workbench icons.

 cybergraphics Revision 40.106
 ------------------------------
   - improved speed auf RECTFMT_LUT8 WritePixelArray()/cybergraphics call
     on 15/16 bit rgb colour screens. Apps like Frodo4.0 which use
     WritePixelArray/RECTFMT_LUT8 may gain a litte speed due to the
     optimized call. Stack usage increases though.

   - BitMapScale()/graphics patch trashed 68k data register D7 in some cases.
     This is now fixed.

 cybergraphics Revision 40.105
 ------------------------------
   - improved speed auf RECTFMT_LUT8 WritePixelArray()/cybergraphics call
     on 8 bit screens. It should be as fast as WritePixelArray8()/graphics
     patch now. Apps or games which have cybergraphx support and use
     WritePixelArray/RECTFMT_LUT8 instead of WritePixelArray8 may gain a
     litte speed due to the optimized call.

 cybergraphics Revision 40.104
 ------------------------------
   - added some code to get powersnap working on truecolour screens

 cybergraphics Revision 40.103
 ------------------------------
   - Due to a bug in the rect filling code, swapping/toggling of simple refresh
     windows got really slow unter truecolour screens with previous v2 versions.
     There is really a VISIBLE speed INCREASE with that fixed now when using
     simple refresh windows.

   - added flood()/graphics replacement. Programs like PPaint should now work
     completely without chipram when cybergraphics/PLANES2FAST=1 

 cybergraphics Revision V40.95
 ------------------------------
   - fixes serious bug in FillPixelArray (register A6 was trashed under
     certain conditions)


 cyberintuition Revision V40.34
 ------------------------------
   - the tags SA_Draggable,SA_DClip,SA_BlockPen,SA_DetailPen are
     now supported correctly
   - fixed some problems with 8bit screens when no SA_Depth tag
     was supplied and the NOCHIPSCREEN is enabled
