make RenderMaskPrimitive2DPixel() clip using clipping (tdf#140797)
The original implementation had this peculiar idea of implementing
clipping using transparency, which slows everything down, because
contents need to be copied and then alpha-blended. Keep that only
for when edges of the clip are to be smoothed.
As a side-effect this also seems to fix tdf#115843 again.
The commit also adjusts the test for tdf#133477 to not rely
on the rounding introduced by the optimization from tdf#115843.

It isn't Skia related, because without Skia I see the same problem

Lubos, could you look at it please?
