    window: remove the small screen code
    
    Because the old layout was never meant to scale well on low
    resolution displays, we had to introduce code that adapts the
    window to be usable on low res screens.
    
    The problem with this code is that it still doesn't scale down
    very well for really low resolution screens. Partially because
    of the layout itself (which, again, was never meant to), partially
    because the panels request a size bigger than e.g. 720x480. Now,
    this is an important feature and we need to support that low
    resolution by default.
    
    To push this constraint forward, remove the code that managed a
    custom mode for low resolution screens. From now on, the Control
    Center shall be adapted to scale well on any screen sizes.
