after the gwc improvements backport (post 2.1.1), 2.1.x use the same rendering routine than GeoServer itself to create the tiles out of the metatile RenderedImage. It actually calls RenderedImageMapResponse.write(...). So there should be no difference, if GeoServer's WMS can render it, then GWC can. AT LEAST there's some misbehavior depending on whether RenderedImageMapResponse.write(...) receives a RenderedImage or a BufferedImage (gwc gives it a RenderedImage product of a JAI crop operation. But I doubt that'd be the case, as there are all kinds on clever tricks inside the RenderedImageMapResponse to account for that kind of things?
