Not until we have the multi-CRTC event support please. :\ I don't want
to have divergent event paths for atomic-but-useless-events.

I've been frantically typing up support for this in Weston (actual
proper atomic modesetting, which is difficult when you have fiercely
independent per-output repaint loops, but seems ~mostly done but for
typing), which I'd hoped to have done a week or two ago but got
derailed due to being sick. It's coming just as quickly as I can type
it tho.

Cheers,
Daniel
