Windows 10 windows contain an invisible area within the NC window frame
on which the mouse cursor is enabled to perform resizing. This change
captures the geometry of the invisible margins and considers it when
moving a window, so that, for instance, a move(0,0) does not generate
gap between the window and the beginning of screen.
[ChangeLog][Windows] The dimensions of invisible margins inside the
frames of Windows 10 windows will now be disregarded in the positioning
of Qt windows to avoid a misplaced look (offset by a few pixels from
the expected position).
