This is redundant. Formats are never FBO-attachable if we don't have
FBOs. It's not clear this is what you want either way though. This
pretty much looks like a copy/paste from fbo_blit_supported(), and the
WINED3DUSAGE_RENDERTARGET check there is to allow formats that don't
have a FBO-attachable internal format, but were created with the
rtInternal format (which should always be attachable). There's really
no equivalent check for backbuffer ORM, it just renders something and
hopes we can read it back.
