Thanks for the reference. I would never have figured that out. When setting
CAIRO_EXTEND_PAD, things are fast even with the latest git driver.

I don't actually care about the behaviour at the border, since it always is
outside the screen. Would you reccommend to render the image to RGBA instead of
RGB, to increase the chance to get an accelerated transformation also from
other hardware?

We really don't want to hit such a slower-than-software fallback. It makes
MyPaint unusable, while pure software rendering would still be very fast.
