------- Additional Comments from Dirk Schulze <krit at webkit.org>
Added support for clipToImageBuffer by using the composite operator
CompositeSourceIn. This is a easy way to support it, with a minumum of code
changes to WebKit.
We need a new Layer for a composite operator, to ensure that we don't influence
the drawing before and after the masking. Therefore I added a new method
closeClipToImageBuffer.
