------- Additional Comments from arno. <a.renevier at samsung.com>
in this patch, we use access data directly if we have an image surface.
Otherwise, we create image surface and copy data from (or to) it. This is
already the current underlying mechanism, but it's made more explicit. Also, we
create the temporary image surface with the minimal needed size. This reduces
data transfer
