gpu: fix off-by-a-half clipping

Browse Source

I don't know why the 1/2 factor is there, but it leads to images being
rendered with a 0.5 pixel offset.

Remove the other useless checks while here: clipping 1px images shouldn't
be a problem and the destination rectangle is always non-zero (otherwise
it wouldn't be rendered).

Update the reference images that are subtly changed because of this fix.
