Since clipToImageBuffer is mac specific, other platforms would benefit if we could remove it from the project.

I did some measurements on mac and Qt-Linux with the following filter combination: <feFlood result="a" flood-color="red" flood-opacity="0.5" x="0" y="0" width="800" height="600"/> <feFlood result="b" flood-color="green" flood-opacity="0.5" x="0" y="0" width="800" height="600"/> <feComposite id="test" in="a" in2="b" operator="in"/> Mac is unaffected by this change, but Qt is 10% faster (full browser).

Comment on attachment 126507 [details] patch r=me, this is a first step towards killing clipToImageBuffer, thus resolving some Qt crashes that recently appeared in that area.
