Running a game on a 2-screen computer with different scales will result in the game shrinking or growing indefinitely

[vchelaru]

1. Have a 2-monitor setup
2. Set the scale% on one to 125%
3. Run the game on one
4. Drag the game to the other screen

Observe - game shrinks or grows indefinitely
Expected - game should stay the same size

This is not a FlatRedBall bug, necessarily, but instead a bug caused by underlying MonoGame:

There is a workaround in monogame here:

MonoGame/MonoGame#7844

It seems like this is specific to DesktopGL and not the DirectX version of MonoGame, so this could be solved at the FRB engine level by adding a new version of FRB which either uses:

• MonoGame DX
• FNA - although this hasn't been tested, it's likely not reproducing there or likely to get a fix if so

I'm going to leave this issue open until we make a new version of FRB
