I have found that rendering to the screen provides far better results than
rendering to IDLgrBuffer (IDLgrBuffers are rendered using the software
renderer). And better graphics adapters will do the anti-aliasing for you
(check your graphics adapter settings). Render to the screen, read the
window, and save as PNG.
