deprecate usage of QDesktopWidget for going fullscreen

Browse Source 
Idea works as follows, while going fullscreen we compare the current window geometry with
available screens and ask for an intersection rectangle, we go fullscreen where most of
the window is located

GuessCurrentScreen could also potentially be used to see which screen
the window is on for dynamic DPI handling
