Code review comment for lp:~smspillaz/compiz-core/compiz-core.lim

I've tested it, to be even better, maybe you could also sync the title geometries once you opened/closed the menu, but that can be optional.
One thing you need to fix is the double-click over the title, that currently doesn't work as expected.
Look at the logic I've used in PanelTitlebarGrabArea.

Then I guess we need to define with design better one case: if a window is unfocused, and the user presses over the title / icon, should we just focus it or also open the menu? Currently we do both, but I'm not sure this is the best choice.
