Code review comment for lp://staging/~saviq/unity-2d/unmaximize-on-drag

Hi Michał,

Thanks for your work. It works well here, but there are a few changes in the code I would like to suggest:

- The code you added to ClosedMenuBarHelper should be in MenuBarWidget: I would like ClosedMenuBarHelper to remain a small helper class to notice when a menu in the menubar is closed.

- Prefer using "const QPoint&" instead of "QPoint*" in WindowHelper::drag() and in MenuBarWidget::menuBarDragged(). Using QPoint* makes it look like the code is going to modify the point.

- Prefer using a forward declaration of QPoint class in windowhelper.h instead of #including it.

- I am worried with r564: it looks like a duplication of the code you added in MenuBarWidget. Maybe it is possible to do most of the work from MenuBarApplet?
