L. David Baron ecd4ba7a2e Bug 1030604 - Use nsChangeHint_UpdateOverflow for clip-path and mask changes so we update the PreEffectsBBoxProperty and run the effect on the correct area. r=roc
The testcase is a slight simplification of dholbert's testcase 2
(attachment 8456312) in the bug.  It fails in the reftest harness
without the patch, and passes in the reftest harness with the patch.
