[mythtv] Multiple screen setups

Trying to resolve a ticket:
without breaking anybody's multi-screen setups
(I don't have multihead Linux test hardware)
These are all the different multi-screen
scenarios I can imagine:
1) Xinerama or Mac OS X. One big virtual screen.
QApplication::desktop()->width() and height() span all.
2) Non-Xinerama. --display:0.N can
select an individual screen.
3) Windows. A am assuming the DirectX stuff
works like Xinerama. Dunno about D3D.
4) Direct FB. Barely supported.
Don't know if multi-screen is possible
I have a patch in that ticket which basically
enables the Xinerama-type settings even if
the screen isn't managed by Xinerama.
At the moment, X non-Xinerama users have to use
--display arg to select a different screen.
Markus has pointed out that my patch seems to
get the wrong geometry if users change their
desktop layout frequently, so it needs work.
(Ideally, -O XineramaScreen=-1, or 0 or 1
would work, but at the moment it doesn't)
If a few multi-screen users could experiment
with this patch, I would appreciate it.
P.S. Déja vu - I last hacked
"multiple screen sanity" early 2005!
