This happens due to an attempt to blit from a 4x4 (STAGING) BC1_UNORM texture
to the 2x2 (and 1x1) miplevel of a (DEFAULT) BC1_UNORM texture. This results in
us passing a 2x2 rect to glCopyImageSubData(). Unfortunately, Mesa also
complains if "fix" the rect to 4x4. The spec is not exactly clear about which
is valid, if either. On the other hand, this is the 8th (and 9th) miplevel of
the texture, so not particularly likely to be breaking rendering.
