Subject: Package building for QNX6

I'm just completed the package description file for QNX6 - qpg, it is like a\
.spec files for Linux. Please place SDL.qpg.in file in the root of the proj\
ect, where .spec file is placed. And sdl12qpg.diff - just adding the SDL.qpg\
.in. The same for the SDL_image. I'm planning to add .qpg files creation for\
all SDL* projects.

As for shared library building for QNX6. It is very hard to improve the exis\
ting libtool code to support QNX shared libraries. Much easyiest is to remov\
e libtool.m4 code from the acinclude.m4 for those persons, who building shar\
ed libraries for QNX6. I'm described all what they need to do with .so under\
QNX6 in the README.QNX file. And 90% of people used the precompiled librari\
es, so I think it is not big problem :)

Subject: Patches for tests and QNX6

Here more fixes for the QNX6 in sdlqnx.diff file:

- Spellchecked README.QNX (thanks to Julian Kinraid)
- Fixed bugs in fullscreen mode: window region wasn't on top by default, so \
it caused some artifacts to be appeared on the screen, prevent window conten\
ts default filler in Photon while in fullscreen mode, it damages the screen.
- Added support for the SDL_VIDEO_WINDOW_POS, SDL_VIDEO_CENTERED env variabl\
es.
- Some minor code restructurization.

Subject: Re: [SDL] [patch] MMX alpha blit patches with MMX detection

I think everything is correct now. I've done as much testing as I could,
but some real-world testing wouldn't hurt, I think.
The patch is here : http://icps.u-strasbg.fr/~marchesin/sdl_mmxblit.patch

If you do byte-by-byte comparison of the output between C and MMX
functions, you'll notice that the results for 555 and 565 RGB alpha
blits aren't exactly the same. This is because MMX functions for 555 and
565 RGB have an higher accuracy. If you want the exact same behaviour
that's possible by masking the three lower alpha bits in the MMX
functions. Just ask !

I removed one MMX function because after I fixed it to match its C
equivalent, it revealed to be slower than the C version on a PIII
(although a bit faster on an Athlon XP).

I've also added MMX and PIII replacements for SDL_memcpy. Those provide
some speed up in testvidinfo -benchmark (at least for me, under linux &
X11).

Subject: bug in SDL_GetRGB/GetRGBA

There's an embarrassing bug in GetRGB/GetRGBA which apparently has been there
for years. It incorrectly converts colours with < 8 bits/channel.
It came to my attention today in #sdl.

What it does now is (for each channel):

rv = (pixel & fmt->Rmask) >> fmt->Rshift;
*r = (rv << fmt->Rloss) + (rv >> (8 - fmt->Rloss));

which is wrong; the last line should be

*r = (rv << fmt->Rloss) + (rv >> (8 - (fmt->Rloss << 1)));

Subject: RISC OS patches

This patch includes a patch to configure.in for RISC OS cross compiling
which was somehow missed from last time.

It also corrects BPP setting and checking behaviour.
