When opening the window menu without an associated control - e.g. by right-clicking the titlebar or by keyboard - using coordinates for the menu position is appropriate. However when the menu is associated with a window button, the expected behavior in the shell can be implemented much easier with the full button geometry: the menu will point to the center of the button's bottom edge rather than align to the left/right side of the titlebar as it does now, and the clickable area where a release event does not dismiss the menu will match the actual clickable area in mutter. So add an additional show_window_menu_for_rect() function and use it when opening the menu from a button. https://bugzilla.gnome.org/show_bug.cgi?id=731058
