screenshot of fire rendering

Some doom3 effects like slightly warped objects behind the fire and glass
windows aren't rendered correctly on evergreen with r600g (high quality effects
should be enabled in the game settings to reproduce). It was not very
noticeable before the commit d1b8f8e8b3b41ab6092fa3f18a4891a0198f64de "r600g:
don't lookup a vs semantic for position/face", but after that commit it is much
more visible.

evergreen+ asics don't support FS_COLOR0_WRITES_ALL_CBUFS yet.  It needs to be
emulated in the shader rather than set as state.

No, rendering of the effects is not changed with that patch. The only change
afaics is the huge performance drop (2-8x) even in the game menu.

BTW, If you don't have the game then there is linux doom3 demo (460mb)
available to download from idsoftware ftp site -
ftp://ftp.idsoftware.com/idstuff/doom3/linux/doom3-linux-1.1.1286-demo.x86.run
-but it was very slow download when i tried it, so you would probably want to
find it somewhere else to download faster. This issue is reproducible with the
demo too. 

Also, I don't know if it would help, but IIRR there were shader sources with
descriptive filenames and comments somewhere in the pk4 data files (probably
pak000.pk4 in the full game, and in the demo there is only one pk4 file. pk4
files are zip archives).
