Bound window width height position

[qwoprocks]

Description

As per title. I also fixed a small bug where the default view in the widget view box could be scrolled.

Fixes #353

Testing

Tried changing the preferences.json to some ridiculous values and the display still turns out fine, according to the bounds.

Remarks

NIL.

Used this for testing, works well. Window size was restricted to the current screen size (used a multiple monitor setup where it snaps to the full size of a particular monitor)

Might want to add a logger statement to display such shenanigans happening?
