This seems like something that should be its own patch. Did you check
if a 2D texture -> cube texture copy works, both on Windows (are we
required to support it) and in the current implementation?

I guess your intention is to avoid having a type == TEXTURE || type ==
CUBE_TEXTURE kind of construct, but technically you'd also have to
check for WINED3D_RTYPE_BUFFER. I'd prefer whitelisting known good
resource types.
