Hi,

Overall, did you check if there is a capability reporting problem? The
game may have the bad size from our DDSCAPS structure.

Even if this is a capability problem I think this test is relevant.

Please add new tests to ddraw{1, 2, 4, 7}.c, and if possible implement
them for all ddraw versions.

Related to that, I don't think the maximum texture size can be larger
than the maximum surface size, and there's a small chance that the
surface's memory pool has some influence on this.
