------- Additional Comments from Dirk Schulze <krit at webkit.org>
FilterEffects need an own ImageBuffer to make it possible to reuse the result.
SVGResourceFilter calculates the filterRect and the primitiveRect and draws the
referenced object into a ImageBuffer. We need this ImageBuffer to get the
SourceGraphic and SourceAlpha.
