[gtk/offscreen-fixes: 2/5] gsk: Add another test

[Matthias Clasen <matthiasc src gnome org>]

commit 1668c7b125a4b5564deb3a72594569559339cec9

    gsk: Add another test
    
    Compare clipped repeat nodes. Must skip cairo here
    since it blurred the child by scaling after rendering.
    
    This currently fails in the gl renderers. since they
    don't correctly handle preexiting offsets in offscreen
    rendering.
