[PATCH 1/5] wined3d: Allow (some) blits with fixups in the arbfp and ffp blitters with ORM_BACKBUFFER.

[Henri Verbeet]

When using ORM_BACKBUFFER, formats with fixups may need to be loaded into
WINED3D_LOCATION_DRAWABLE. Before commit
cad4badbcf25992e0c61521aa15e639c2611f5d6, 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.
