Only deals with rendering tiles. If you don't like Dplug default compositing, just make another Compositor and assign the 'compositor' field in GUIGraphics. However for now mipmaps are not negotiable, they will get generated outside this compositor.
From given input mipmaps, write output image into wfb with pixel format pf, for the output area area.
Setup the compositor to output a particular output size.
