While I very much agree that we need a mechanism for things like that
(include antialiasing, anisotropic filtering, vblank, etc. here), I'm
not entirely sure that this fits the RandR extension. Many of these
parameters are not output dependent, but card and/or host dependent
(read the later: global).
