fix softmask bug when the ctm changes

I've found another bug in the cairo softmask code. It was not correctly
handling the case where the ctm changes after the mask is created and before
calling cairo_mask().

The attached patch fixes this. This fixes bug 28637. It also makes the ducks
and roses pdf in bug 22098 render almost correctly. I'm still investigating the
remaining issues with the ducks and roses pdf but it appears the problem is in
cairo, not poppler.
