awin 1.0.13

Short:        Easy-to-use API for RTG chunky display
Author:       no-email@for.now (Harry "Piru" Sintonen)
Type:         dev/c
Version:      1.0.13
Requires:     MC68020, OCS, Kickstart 3.0 (see awin.doc for compiling req)
Architecture: m68k-amigaos; ppc-powerup

Important: I am having my military service till 31th December 1999,
so I might not be as active as before. You can find me from IRC
occasionally as Piru (on channels #amiga, #AmigaFIN, #amycoders and
so on) though. CU on next millenium. ;)

Major changes in 1.0.13:

 - implemented real CGFX/P96 16bit for window and non-directdraw
   screen mode. to try it set option `useargb16 on'
 - depth 16 8bit emulation had wrong palette in >8 bit screen
   modes. fixed
 - awreadargs had a bug: it wasn't able to clear any awodargs
   flags. fixed
 - depth 16 directdraw bugged. fixed

awin is a easy-to-use API for RTG chunky display. It is intended
to be used with games, demos and gfx intensive applications
(could be used with scopes, screen blankers, etc.).

This archive contains full sourcecode to awin. Read awin.doc
for more details.


Also there is a simple demo program included awindemo.c, see
Makefile and SMakefile.

Initially this demo opens a window with 320x240 innersize and
shows simple `pseudo'plasma, rotatezoomer and tunnel effects.
For info about some awin commandline features do
`awindemo68k ?' or `awindemoppc ?'.

Both awindemo68k and awindemoppc load bunny.pal, bunny.raw,
glas2.pal and glas2.raw.

awindemo68k requires minimum MC68020, OCS, Kickstart 3.0 and
SetPatch.

Additionally awindemoppc requires ppc.library V46.6+ and
naturally PowerPC processor.


IMPORTANT! As I ran out of time some features of awin are
untested, remarkably: cgxvideo.library support. Also some
things I would have wanted to implement and some m68k
optimizations are missing (that is those routines have only
c versions included). Probably there is some bugs in it, too.

P.S. I will have my military service from January 4th 1999 on.
It would be great if someone would take over awin development
meanwhile. That is to do some stuff mentioned in awin.c todo
section + other fixes and improvements and test it carefully
and then upload updated versions to aminet.
