Xglx might report the Xinerama monitors as separate screens by just
creating one glx window per monitor. I don't know how window movements
from one Xgl screen to another will be accomplished, maybe by extending
the fixes extension to allow reparenting windows from one screen to
another or by using the future coordinate transform extension to
redirect input events back to the screen the client is connected to.
