Changes for 41.8 (r65 archive)

- added new LVO to cybergraphics.library to write chunky pixel arrays with custom
  colormaps to truecolour screens
- new LVO added to cgxsystem.library to give applications access to the list of
  installed graphics devices
- if a OpenScreenTags()/intuition tag SA_ColorMapEntries is detected with
  a data value greater 256 it is limited to 256. This fixes some problems with
  truecolour screens in conjunction with certain applications (e.g. gmultiview)
  that are always trying to get 1<<depth entries.
- BltBitmap()/graphics calls with mask=0x00 are never passed to the gfx
  card drivers anymore.
- You can now click "through" transparent regions of a layer
- Fixed a bug in the HideWindow()/cgxsystem.library call
- If SUPERLAYERS is activated can be checked by searching for the public
  semaphore "SLayerSemaphore" now

Changes for 41.7 (r64 archive)

- new LVOs added to cgxsystem.library to allow for easy support of window
  iconification. Windows can be hidden by a simple call now (SUPERLAYERS only)
- added new LVOs to cgxsystem.library to let applications support transparent
  regions inside layers (SUPERLAYERS only)
- DoCDrawMethodTagList()/cybergraphics did not work at all actually because
  the supplied hook was never called. Fixed.
- mouse pointer hotspot changes due to modification of the HIRESCRSR env
  variable take now effect immediately.
- all aga sprite resolution related mouse pointer hotspot problems should
  be fixed now (e.g. PageStream3/Iconian cross hair)
- CModeRequestTagList()/cybergraphics.library now correctly returns a 0
  instead of -1L/INVALID_ID if the mode requester is canceled
- fixed a serious problem with screen dragging in conjunction with updating of
  next screens. If the front screen was dragged down while there was something
  updated in the background the system could crash.
- blitting of LUT8 format src bitmaps to rgb destinations maps crashed
  immediately. Fixed.
- BestCModeIDTagList()/cybergraphics now always returns the displayid of the 
  first graphics board available of that kind if the CYBRBIDTG_MonitorID tag
  is specified. If multiple boards of the same kind were installed, it always
  returned the last board available in most cases before.

Changes for 41.6 (r63 archive)

- SUPERLAYERS could return 0 with some NO-OP layer operations. Now intuition 
  requesters should work properly.
- Layer damage code in SUPERLAYERS ScrollRaster patch rewritten
  Now every exotic situations should be handled properly.
- Discovered that some code "out there" relies on a private field in
  layer structure, which was changed with SUPERLAYERS. The old field
  is now supported and this causes for example MUI complex 
  virtual groups to scroll more smoothly.
- ScalePixelArray()/cybergraphics now uses the blitter for line replication
  in source mode RECTFMT_LUT8 and RECTFMT_ARGB whenever possible.
- fixed a bug in DoCDrawMethodTagList()/cybergraphics. The supplied hook was
  always called with the parampacket and the object swapped.

Changes for 41.5 (r62 archive)

- fixed a memory leak problem in the color extraction code for
  Flood()/graphics operations. A certain buffer was not freed.
- extracting certain pens on planar rastports didn't work at all for
  Flood()/graphics operations. Now fixed.

Changes for 41.4 (r60 archive)

- fixed a bug with computation of free video memory in OpenScreenTagList()
  patch

Changes for 41.3 (r59 archive)

- modifed graphics.library color function patches, to avoid possible problems
  on systems with multiple graphics boards installed.
- modified CVideoCtrlTagList()/cybergraphics to avoid possible problems in a 
  multi monitor system.
- CVideoCtrlTagList()/cybergraphics waits for the vertical blank period now
  until it applies the given tags to the viewport

Changes for 41.2 beta6 (r58 archive)

- Complement draw WritePixel()/graphics now correctly works under rgb
  colour screens. This fixes e.g. some problems with the various circle
  tools of ImageFX/Photogenics/PageStream3.1 etc. when used with screens
  that have more than 256 colours.

Changes for 41.2 beta5 (r57 archive)

- fixed a problem with the mousepointer moving to fast. This problem
  was introduced with cgxsystem.library 41.2 beta4
- WaitBOVP() and AllocDBufInfo() graphics patches were accidentally
  removed in cgxsystem.library 41.2 beta4. fixed

Changes for 41.2 beta4 (r55 archive)

- fixed the "mouse pointer can't be moved beyond position 1363 in
  x direction" problem
- modified CoerceMode()/graphics patch to return the real viewport
  display id instead of the base monitor id in case of a cybergraphx
  mode
- added some new lvo's to cybergraphics.library for CyberGL
- fixed some problems in the view related code that should cure
  some trouble with native amiga modes used like in ScalaMM or
  ProDad's SSA Player.
- fixed a bug in the RGB24 3BPP cpu masked pattern blit code
- fixed a bug in the RGB15PC fmt writepixel code (used by PII)
- optimized cpu bitblit code for 3BPP rectangle copies
- added a new call to the cybergraphics.library interface
- optimized cpu filling code for 3BPP rectfills
- fixed a bug in the RGB24 3BPP line drawing code

Changes for 41.2 beta3 (r54 archive)

- Scrolling of superbitmap layers speeded up a lot with Superlayers
  enabled. Now uses the blitter whereever possible.

Changes for 41.2 beta2 (r53 archive)

- Fixed a D2 data register trashing problem with BltBitmap()/graphics
  0xc0 minterms on truecolour bitmaps.
- added support for superbitmaps in Superlayers and fixed some damage
  region related bug in Scrollraster()/graphics patch
- fixed conversion bug with RGBA/ARGB scaling in ScalePixelArray()/cgx
  when destination bitmap format was RGB15

Changes for 41.2 beta1 (r52 archive)

- Superlayers now support smartrefresh in all weird clipping and damage
  cases.

Changes for 41.2 (r51 archive)

-  added  new  layers  replacement.   Should  speed  layers  up  a  lot,
   especially when sizing layers.  It is disabled by default, you have to
   set envarc:cybergraphx/SUPERLAYERS to "1" to enable it.  At the moment
   this superlayers is in beta-state, and some work still has to be done.
   SuperBitMap layers and custom clipping to offscreen smartrefresh buffers
   are not done yet.  So use this BETA-OPTION at your own risk, and if it
   doesn't work, disable it and wait for later releases.

Changes for 41.1 beta9 (r50 archive)

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

Changes for 41.1 beta8 (r49 archive)

- internal changes in MovePixelArray()/cybergraphics. Should now work
  with layered RastPorts, too.
- added optimized code for drawing circles in hi/true colour modes
- increased writepixel output speed for  hi/true colour modes.

Changes for 41.1 beta7 (b47 archive)

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

Changes for 41.1 beta6 (b46 archive)

- 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.

Changes for 41.1 beta5 (b45 archive)

- 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.

Changes for 41.1 beta4 (b44 archive)

- fixed "test screen to small" problem introduced with beta2

Changes for 41.1 beta3 (b43 archive)

- added some code to get powersnap working on truecolour screens

Changes for 41.1 beta2 (b42 archive)

- added additional planar bitmap checks in BltBitmap()/graphics code
  to avoid some strange effects with certain programs

Changes for 41.1 (b41 archive)

- LockBitMapTagList()/cgx always returned a 0 as handle. Now it returns the
  handle properly.
  This will most likely fix all AmiWin related lockups. 

Changes for 41.0 b362 (b40 archive)

- added support for multiple boards of the same kind. The drivers need to
  have that feature implemented though to use that option.
- fixed some problems with standard menu backfilling when PLANES2FAST option
  is enabled. Please don't use that option when you are not aware of what it's
  doing actually. It reduces compatibility and general stability in some cases.

Changes for 41.0 b348 (b39 archive)

- inlined some code in cgxsystem.library. This will slightly improve speed
  in some areas

Changes for 41.0 b320 (b37 archive)

- added horizontal/vertical lines hw acceleration for gfx boards
  that don't have a special line engine but allow for solid fill.

Changes for 41.0 b303 (b36 archive)

- mouse/screen blankers which blanked the mouse sprite the way the C= blanker
  does, now blank the mouse sprite again properly.

Changes for 41.0 b299 (b35 archive)

- Due to a bug in the rect filling code, swapping/toggling of simple refresh
  windows got really slow unter truecolour screens with v2 and previous
  V3 versions. There is really a VISIBLE speed INCREASE with that fixed now
  when using simple refresh windows.

Changes for 41.0 b291 (b34 archive)

- nextscreens should get updated properly now

Changes for 41.0 b289 (b33 archive)

- This is for all WritePixel/PutPixels lovers out there:
  wasted 20 minutes of my valueable time to increase writepixel output. This
  graphics function is mostly unused with os graphics operation but some people
  really think that the speed of this function is a general speed indicator
  Rather strange ......
- fixed a bug in OpenScreen()/intuition patch. If applications called it with
  other flags besides NS_EXTENDED set in the newscreen.type field, the 
  Extended tag field was ignored. This e.g. fixes some screen opening problems
  with Finalwriter.
- programs which use the SA_LikeWorkbench tag to open a screen correctly open 
  on a cybergraphx display now, if the workbench is opened on a cybergraphx
  display, too.

Changes for 41.0 b270 (b32 archive)

- the mouse crsr is now disabled on the previous view if the active
  view changees to a different gfx card
- fixed a problem with masked rectfills with screens that have less than 256
  colours

Changes for 41.0 beta263

- LoadRGB4/SetRGB4 now behaves like in earlier betas which should fix some
  palette problems with older programs.

- enabled support for 8bit hardware accelerated planar bitmap to chunky
  bitmap blits 

- Truecolour related parts of BltBitmap()/graphics rewritten. Should be 
  faster now under certain cases.
