Hi Maarten,
I've tried to generate a small test-case, however it seems the
behaviour I was seeing was a bug in the old intel-driver I was using
on my production system (2.1.1), and seems to be fixed in git already.
With GIT, intel behaves exactly like pixman :)
Thanks, Clemens

Yes, this one:

Hi again,
Sorry I completly forgot that the black pixels I see are caused by
another bug in the intel-driver, which is only visible on http://picasaweb.google.com/linuxhippy/Mask_Transformation#
So it seems the mask is a moved a bit left/up, thats why pixel show up
which are outside of source-sur

They were created by the Java AffineTransform class.
I just dumped it and copied it into the C file.
I basically get an AffineTransformation instance (set by the "user"),
inverse it and set it on the source.
For the mask I do exactly the same, ex

Yes I created one, http://pastebin.com/f729a71aa
The testcase works perfectly with pixman (even with much higher
scale), but on intel seems the mask has t

Good to know, thanks. I was a bit concerned when mixing both with src and mask.

Hi,
I am compositing a transformed source with RepeatPad (and billinear
interpolation) and a mask (nearest) to get sharp edges.
What I do for now is I draw a rect in the mask as large as the source
and apply the same transformation.
However this requires me to have a mask as large or larger as th
