Type:     gfx/board
Version:  1.24

This archive contains all you need to get Picasso96 up and running on your
Amiga.  Picasso96 offers support for many different Amiga graphics boards,
has  builtin  HiColor and TrueColor support for intuition screens and many
more...

Requirements:
- Kickstart and Workbench 3.0 (V39) since Picasso96 v1.17,
- Motorola MC68020 processor or better,
- CyberVision 64, Domino, Merlin, oMniBus, Picasso II, Picasso II+,
  Picasso IV, Piccolo, Piccolo SD64 or Spectrum.

AnyWare, i.e. not commercial or ShareWare. No distribution restrictions.

Short history:

Changes in 1.24:
- corrected checks for maximum BitMap size that may be put to the board.
- CV64: some minor speed improvements, corrected sync polarities and screen
  clearing.
- changed screen mode name for 8 bit modes for better sorting.
- lots of speed improvements on the Cirrus GD5446 (as used on the PicassoIV).
- finished BltPattern() with masks in Hi/TrueColor (ColorWheel should finally
  work on all screens as expected).
- mouse sprite speed is now the same for all sprite resolutions.
- detecting of empty software mouse sprites implemented.

Changes in 1.23:
- further on-board hardware-blitting support implemented.
- friends to bitmaps already on the board will be allocated on the board,
  too, especially clip rects. This in combination with the new on-board 
  blitting functions can lead to dramatically improved layering operations
  if there is enough off-screen memory available on the board. So you
  might think twice before spending all board memory for large and/or
  TrueColor screens... :-)
- improved management of on-board memory.
- to take advantage of the new features, some S3 driver blitter functions
  had to be rewritten and may be a little bit slower now. This also fixes
  some potential problems with small screens at the end of the board
  memory due to restrictions caused by the way the blitter has to be
  programmed and leads to more efficient memory usage.
- fixed rounding and pixel clock slider (edit screen) in Picasso96Mode.
- PiccoloSD64: improved timing and fixed ZorroII planar2chunky bug.
- fixed two color chunky screen layering bug.
- changed naming scheme for screen modes to give more detailed 
  information on the different modes (limited to 31 characters by the OS).
  The display IDs are still the same, so only a few braindead programs
  should notice.

Changes in 1.22a:
- included new version of picture.datatype
- replaced invalid GD5434 chip driver

Changes in 1.22:
- bug in BltBitMap fixed, Workbench now displays directories using
  "View By Name" method correctly even in Hi- and TrueColor,
- bug in GetColorMap() fixed which made trouble pinting in color from
  within various applications,
- PicassoIV driver and FliFiTool now support PicassoIV.resource versions
  upto 4.1,
- if you use a SoftSprite with PicassoIV, it will no longer disappear over
  PIPs,
- sanity checks added for PIP stuff,
- CV64 hires sprite in TrueColor fixed,
- CV64 and SD64 planar to chunky conversion hardware support added,
- Picasso96Mode now displays an extra timing parameter window on the "Edit"
  screen and preserves future monitor data chunks written by PMTNG and
  maybe even Picasso96Mode itself...
- the Picasso96 installation comes in a separate directory now.

Changes in 1.21:
- fixed bug which resulted in BMF_CLEAR being ignored in various cases,
- fixed bug with fonts using italic soft style on non-layered rastports
  (Commodore did not adhere to its own programming guidelines there...),
- no normal user should ever be annoyed by debug output again from now on.

Changes in 1.20:
- Direct2Chunky and Direct2Planar blits now work by pen comparison. At least
  PowerSnap works with Hi- and TrueColor screens now...,
- fixed AllocBitMap() which did not clear bitmaps in some cases,
- fixed bug in Draw() that did not reset some chip registers on planar
  displays,
- fixed bug in internal DisplayID handling that could cause lockups,
- added DisplayID sanity check to avoid DisplayIDs from being used twice,
  resulting in system lockups,
- fixed fastlayers.library which caused crashes on some systems,
- planar modes supported with PicassoIV now,
- added byteswapped modes with PicassoIV in ZorroII amigas
