Ok, I'll send in a patch to fix this.

The problem is that Microsoft changes what D3DFORMAT are valid between Direct3D releases, DirectX
9 is missing some formats that are in DirectX 8 and DirectX 8 is missing some formats that are in
To work around this a new enum WINED3DFORMAT was created that includes all the types valid for
DirectX 8 as well as those valid for DirectX 9. Because DirectX 8/9's D3DFORMATs are a subset of
WINED3DFORMAT DirectX 8/9's D3DFORMAT can be cast to WINED3DFORMAT without any problems.
Texture states are similar to this, except that when DirectX 8 is moved over to using wined3d a
switch will be required to send those states that are sampler states in DirectX 9 to wined3d
SetSamplerState instead of SetTextureStageState.
