WinGUI Nightly 20210511210419-edb7bbe94-master - Dimensions Tab: Maintain Aspect Ratio Broken (Bad Math)

[Synapto]

Problem description:

I'm referring to the functionality of the Keep Aspect Ratio toggle checkbox, renamed to "Automatic" in the latest nightlies.

1. "Display Size: 0, Aspect Ratio: 1:INFINITY"
   Doing nothing except clearing the "Automatic" checkbox under "Final Dimensions:" produces a Display Size of 0 and a correspondingly calculated Aspect Ratio of Infinity.

2. "32" Everywhere
   Doing nothing except selecting Anamorphic: None or Custom, then clearing the "Automatic" checkbox produces a Scaled Size: height of 32. If you then clear the "Optimal Size:" checkbox, you can modify that obviously borked height value and watch the width value instantly bork itself to 32 as well.

In version "20210528-29b73dcaa" issue with "Anamorphic" set to "None" and "Final Dimensions - Automatic" set "off" and "Scaled Size" value forcing values "32/34" is not solved.
There is no way to manually set final picture dimensions with "Anamorphic" set to "None" (PAR 1:1), which is best when resizing.

Should be now.
