Description
Currently Prism support rectangular clip only. I'd like to request support for clips that are arbitrary Paths. Something like
  Graphics.setClip(Path clip);

Webkit uses shaped clip extensively, so in WebView we have to work around by rendering to an offscreen image and blending with mask. This is very inefficient.

Attaching the WebViewer.java app that can help with measuring the rendering time when used with the sample.html files attached to the dependent bug report RT-24994.

Not completely sure, but I'd say we don't. We currently do blending with a mask, and the result seems fine.

Do you need soft edges on this clip?
