As a first cut, my plan was to simultaneously generate postscript output and render to a page-sized image at printer resolution (mondo huge). Areas which PostScript could acurately render would be drawn with postscript, other areas would be sent as huge images. Optimizing that to avoid the huge buffer by saving data in some metafile format might be generally useful, both to avoid the giant pixmap unless necessary and also to permit striping of the output. Hmm. We could specify a metafile format and require a post-processing stage to convert that for the printer. In the best of all possible worlds, that format could be PDF... -ketih
