st/mesa: provide GL_OES_copy_image support by caching the original ETC data
The additional provision of GL_OES_copy_image is that it work for ETC. However many desktop GPUs don't have native ETC support, so st/mesa does the decoding by hand. Instead of discarding the compressed data, keep it around in CPU memory. Use it when performing image copies. Signed-off-by: Ilia Mirkin <[email protected]> Acked-by: Marek Olšák <[email protected]>
