When using ORM_BACKBUFFER, formats with fixups may need to be loaded into
WINED3D_LOCATION_DRAWABLE. Before commit
cad4badb, surface_load_drawable() would always
use the device blitter, without checking whether the blitter actually supports
the blit. The FBO blitter would be able to handle these blits, but is
unavailable when using ORM_BACKBUFFER.
