I tried it with rotation, using a 100x scaled 2x2 image as source
(that why it looks like a gradient) and for me it looks quite good.
I tried it one time with a nearest filtered mask (no AA) and one time
with billinear filtering (AA):
For the demo the scaled source picture is much larger than the drawn
rectangle, but shouldn't this work once REPEAT_PAD is implemented in
