There are very few tests for glGetTexImage. Not hitting one doesn't mean
much.

I don't think this is correct. The check is for compressed textures to
ensure that the texture coordinates are a multiple of the block size of the
texture. I'm not sure what the rules are for 1-D array compressed textures
(if they even exist) bit I'm pretty sure the compression doesn't cross
slices. If anything, we probably want to take the check below that looks
at height and pull it into the if too.
