wine-7.13 crash on Intel Iris Plus Graphics (Ice Lake) with
WINEDEBUG=+d3d,+d3d9,+opengl,+wgl,+seh

For laughs, I tried running the game under vanilla wine-7.13 on a Surface Pro
7.  (Intel iGPU Intel Corporation Iris Plus Graphics G4 (Ice Lake) (rev 07).
FYI, this gets misdetected by wine due to an unknown device ID. I should
probably send a patch for the gpu list...)

The game has never worked for me under wine on this device. It always crashes
on the splash screen even before wine-7.13. (I'll open another bug for this
one, but I'll attach the log here for completeness sake. It has
WINEDEBUG=+d3d,+d3d9,+opengl,+wgl,+seh flags set.)

However, I thought it might give some clues and I think I got a couple. The
game crashes due to a EXCEPTION_ACCESS_VIOLATION error on this device, but it
also echos something else at the last second: "** Downsizing Textures, Over
Budget by : 115 Mb"

I've never seen that message before on my other systems. So I'm not sure why
it's showing up here. (Maybe because it's not an nvidia GPU?) For fun, I tried
running the game under wine-7.11 and there the message appears right before the
D3DXLoadSurfaceFromMemory() unhandled filter fixme spam. Instead of after it as
on wine-7.13. So it seems like we have a thread racing / sync issue.

Looking at the actual fixme complaint indicates that the unimplemented filter
is D3DX_FILTER_BOX. MSDN seems to indicate that it is meant for down-sampling a
texture. (If averaging a group of pixels is anything to go by. Admittedly, 3D
work is not my realm of expertise.) Looking at the wine code
https://source.winehq.org/source/dlls/d3dx9_36/surface.c#2120 we see that
filter is indeed unimplemented. This fixme gets printed a lot even during
normal operation of the game. Despite the lack of the "downsizing textures"
message on my other systems. So perhaps if the filter was implemented the VA
exhaustion issue might get a little better.
