Implements a special case for temporary surface creation for DXT low mip levels.
TRAC #12908
The lowest mip levels for DXT textures will have dimensions < 4, so a D3D
texture cannot be created to hold them offscreen directly. Instead, we must
create a larger texture one of whose mip levels would be the desired dimension,
and store the surface from that texture for later inclusion in the final
texture.
