Well, glReadPixels and glDrawPixels still works fine.  What more frame
buffer access should you really need?

That said, if possible, you should try to use textures instead of
gldrawpixels.  It is likely faster for local use, not to mention
a major boost for network use.  But that isn't always possible.
