Terminal output from 1.1.39

Sonic R has an option to use DirectDraw or Direct3D, and while DirectDraw mode
works fine, Direct3D mode just produces a blank screen. If I blindly navigate
to the character selection screen, I can see textureless character models, but
that's it.

Older AppDB tests for this game show that Direct3D mode worked ages ago, but
this bug appeared sometime between 0.9.35 and 0.9.38. After much reverse
regression testing, I confirmed this and tracked down the problematic commit:

d9fef10b71b9add27cfaeffa6d7e3ab42342bba7 is first bad commit

    ddraw: Some caps fixes.

    Cards at DirectX7 times did not support non power of 2 textures, and
    some games check the capatiblity flags incorrectly. Rollcage expects the
    D3DPTEXTURECAPS_POW2 (limitation) flag set and fails with the reference
    rasterizer which support NP2 textures and doesn't have the cap set.

Since I doubt the patch would still revert cleanly after all this time, I tried
the first version with it included (0.9.37). Vanilla 0.9.37 shows a blank
screen in Direct3D mode; with the patch reverted, the game can be seen, albeit
with graphical bugs (apparently from an even older regression).

My video hardware is Intel GMA 950, driver version 2.9.0.
