Code review comment for lp:~vanvugt/compiz/fix-751605

@smspillaz; yes the gesture preview displaying on the wrong monitor is annoying, but the main issues is that "the window should always maximise on the the monitor that contains the majority of the window at the moment the user gives the maximise command".

Regarding the corner case of the minimum size (*not the current size*) of a window being larger than the available area when in the maximised state, I agree that a nice solution would be to prevent the user from trying to maximise the window in the first place. Yes having the 'maximise' window decoration disappear and reappear is a bit weird, but it is better than either the window maximising when their isn't enough space, or the user pressing the button and nothing happening. Given that this is a very rare corner case I am happy to go for "maximise button disappears when the minimum possible size of the window is larger than the available screen area when maximised" as a solution.
