Window is maximised in wrong workspace

[sid payton]

1. Open an app and unmaximaise it
2. Drag the window to the side of the current monitor, so that the window is on two workspaces. Most of the window should be on the other workspace
3. Double click the window titlebar to maximise the app

= The window is maximised on the other workspace

This only happens when half the window is on a different workspace. So I suppose the overall problem is which workspace owns the window? The active workspace that has any part of a window in it or the workspace that has the window in ti the most?

This would also be a problem in compiz, not unity.

The current system already acts quite intelligent:
It will choose the workspace to maximize on that holds the biggest part of the window...

But this system could be improved, my idea:
We could upgrade the logic to not only take the window's position, but also the mousepointer's position into account.

We would have to be very careful though when to also check the mousepointer's position to not introduce unwanted regressions here: On multimonitor-systems the mousepointer could be on the other screen, while the user maximizes a focussed window per keyboard shortcut for example.

But including the mousepointer' position in the maximize viewport calculation could bring a solution here...

Also a quick peak on the HUD's positioning code could also help as the HUD will never open off-screen.

Simply not allowing off-screen maximizing would be another solution...

Btw, this is a duplicate of bug #776435. I'll mark it as such and add necessary info to the other one.
