 On good-old CRT TVs, with overscan, it seems impossible to adjust the UI
 so that it's entirely visible within the viewable portion of the screen
 (i.e. inside the overscan area) and have crisp edges.

 This is because unlike a normal TV signal which has a picture that is
 knowingly broadcasted larger than the viewable area (and allowances are
 made for that) the myth UI tries to make it's picture _exactly_ the same
 size as the viewable area.

 The problem is that on CRT TVs, this area where the overscan starts is
 never crisp and sharp.

 See the image I have attached for an example.  Notice the "wow" in the top
 left side of the UI border.

 This can be solved by making the UI window stretch larger than the
 viewable area, into the overscan borderd, but allowing the adjustments
 being made to keep the UI inside the viewable area by placing the widgets
 on the canvas tighter together rather than making the whole canvas simply
 smaller.
