The new version of ico in double buffer mode draws the entire window each time the icosahedron moves, rather than just a square region around the icosahedron as the old version did. It doesn't "draw the entire window" in a strict sense, it uses the multi-buffering extension if it exists. The sample implementation of this extension uses pixmaps, and copies the entire buffer on-screen. Does anyone know why it was changed? To provide an example of using the multi-buffering extension. It is, after all, just a demo.
