Funny how there does not seem to be a dummy device that just records the display list. You either need to have a screen device or plot to a temporary file. The gridSVG package will let you capture textual SVG, I think without touching a file. But that's only for grid, and then you have the problem of rendering the SVG ;) Deepayan's Qt device can capture any kind of graphics in any format, but that requires Qt. Too bad the file devices do not support connections... would make capturing png easy.
