Added the area (Rectangle) to the FastBitmap, this made it possible to convert the current filters (all but the BlurFilter, this I want to review). Still want to see if I can change the way the filters work, maybe I can prevent some extra bitmap actions by changing the flow & signatures... Need to start in DrawableContainer.DrawContent.
