Fix of Filter source position

On SVG Filters, the rest of the source graphic gets clipped to the filter rest.
This helps us to minimize the size of intermediate ImageBuffers. If the
position moves to the right or to the bottom, we have to adjust the
GraphicContext of this intermediate ImageBuffer.
This patch fixes the adjustment of the context, according to the clipping.
