Comment 9 for bug 1287288

>> If two items refer to the same clippath won't the transform be done twice? Also, what if an item is both clipped and masked?

good questions. with respect to the first question I don't know what would happen. I have not been able to produce an example that illustrates that point.

wrt the second question, attached is a file that illustrates the problem. The example fails after the unit change. However I think the fix for this should be relatively simple, and I will investigate it tonight. If there is no objection, I will commit a proposed solution today or tomorrow, if I find one.
