Cairo outputdev problem, works with splash.

Same bug than #16906.

It certainly doesn't _look_ like the same bug as #16906.  Has anyone been able to confirm that the fix for that bug fixes this bug?

Yes, it doesn't look like the same issue, but it is. The problem was in drawMaskedImage, when the image and mask don't have the same size we were using the same matrix which is wrong, the mask was scaled incorrectly. See commit:
