splinter cell demo #2: shadow error in projector mode

Hi there,

I'm currently trying to get Splinter Cell running on my system. After
experiencing some massive problems with the full version I switched down to the
demo versions (there are two AFAIK), and I'm now trying to get the demo #2 to
perform correctly.

I've disabled GLSL and set the OffscreenRenderingMode to fbo.
I also tweaked the Splinter Cell ini a bit, so it uses "shadow projector mode"
instead of "shadow buffers", by changing the line
ForceShadowMode=0
in the D3DDrv.D3DRenderDevice section.

Still I get some visual errors with the shadows. Seems like some sort of
polygon/decal offset problem, see the screenshots for more details.

Also I have the already mentioned "light source bug", which makes some
lightsources shine through massive geometry, I'm also attaching these screens.

The console is still flooded with various error messages about invalid GL
instructions, and so on, also going to attach some logs.

The shifted screen bug (that I reported in this bug:
http://bugs.winehq.org/show_bug.cgi?id=9609 - screenshots already there) also
happens with the demo. If I'm running the demo with 640x480 resolution it
doesn't appear though.

Greets,
Tobias Jakobi
