Current wine and HL2 family - well done!

[Pavel Troller]

Hi!
  Normally I'm writing complaints here, so for a bit of compensation, I would
like to inform that yesterday's wine runs HL2 family of games for the first
time without an annoying graphics glitch causing parts of skies to be
replaced with some bogus contents like white, black, mirrors of a part of
ground etc.
  So, many thanks to all the DirectX developers especially from my sons, they
are very pleased and wish you all the best, especially continuous progress
in wine development (a bit egocentric from them, but nice :-)) ).
                   With regards, Pavel Troller

Yeah, finally no new regressions :-)

The bug you describe used to happen because wine, by default, renders 
offscreen textures on the back buffer and then reads them back. Those parts 
of the back buffer touched by offscreen rendering that aren't redrawn will 
show the contents of the texture. It was possible to fix that by switching to 
pbuffer offscreen rendering before using a registry key. I modified the back 
buffer offscreen rendering to use GL_AUX0 if it is available, mainly to get 
better offscreen rendering on macos, which does not support glx pbuffers.

The end idea is to use frame buffer objects. Support for that is there 
already, but it doesn't work with hl2 yet.
