[sugar] Moving to metacity with composition (was: Preparing for the feature freeze)

[Jim Gettys]

For composition to not eat memory (a full frame buffer's
worth/activity), the buried windows need to be "unmapped" in X parlance.
When a window is unmapped, X can free the contents of the window even
when composite is running (IIRC).

This may require some work in whatever window manager we decide on.
