as a surface with a format of different block width/height (but equal
block size).

pipe_context::create_surface supports reinterpreting a texture as a surface
of a format with different block width/height (but same block size in bits).
For example, a compressed texture image can be interpreted as a
non-compressed surface whose texels are the same number of bits as the
compressed blocks, and vice versa. The width and height of the surface is
adjusted appropriately.
