Since we don't support rendering to compressed formats, we implement this by using a compatible format with the same bpp as the compressed format. However, we need to take into account that the underlying compressed image bpp is computed for a full block, so when we specify regions on the compressed image, we need to divide offsets and dimensions by the block size. This works well for anything that copies to a compressed format using the TLB, but it doesn't specifically address copies from compressed formats to other compatible images. These go through the blit path and require to copy by blitting (texturing) from the compressed format to another format. In this case, we choose a comptible format with the per-texel bpp (not the block bpp) of the compressed format so it matches the setup for the blit operation.
