> 1. Instead of pushing two groups to emulate the image clip, it pushes one (to isolate the mask) and then calls cairo_mask_surface during restorePlatformState.
> 
> 2. Cairo does not composite with the previous group when you push a group. To deal with this problem, I blit the contents of the previous group onto the new group after pushing it. This produces the correct rendering with Andrei's test case.

Did you run pixel tests on LayoutTests/svg/clip-path/? Or even better LayoutTests/svg/ in general?
