If anyone wants to write up some proposed protocol for XFixes, it would
be easy to add the necessary code.

Yeah, we came up with a fairly simple mechanism here which involved
events when clients disabled/enabled the screen saver -- the events
would contain the current disable count. The screen saver application
would *also* disable the automatic screen saver and then would be able
to track other clients disable requests by noticing when the count > 1.

I don't think this requires any DPMS grabs, although a convention
marking screens that have active screen saver applications might be
helpful in avoiding multiple such applications.

We were hoping to get per-CRTC DPMS stuff into RandR this server release
cycle, but it didn't get finished up. That would give the screen saver
application direct control over the monitor power states. I think, along
with DPMS disable events, is sufficient to build a sensible external
screen saver application.

This seems like a fairly serious challenge given the core focus
semantics. Delivering the events is probably easy enough to fix, but
rewriting the focus-in/focus-out event code will probably cause whot to
blow a gasket.
