It's not really clear to me that refusing to create P8 surfaces in
d3d8/9 really gains us much, or that it's really a prerequisite for
the other patches. If you want to go that way though, you should
probably just map D3DFORMAT_P8 to something that's not
WINED3DFMT_P8_UINT, perhaps WINED3DFMT_UNSUPPORTED, and just let
wined3d fail resource creation.
