tried to make the engine retain the user selected resolution

[UbuntuJackson]

I changed 3 files and created preference_data.hpp. You should be weary of my lack of knowledge about how Frogatto treats it's virtual gamescreen sizes. Basically I added an if statement that separates presence and absence of a preferences.cfg. If the file exists, the autoSelectResolution function is not called, because why should the resolution be set automatically when user defined settings exist? Please notify me if my changes require further explanation.
Also here's a video showing off the changes.

why should the resolution be set automatically when user defined settings exist?

Sometimes, when playing on a laptop, the laptop can be docked or undocked. The maximum screen resolution may change then. However... we probably just want a check for that when we load, and if we're trying to load a resolution larger than the combined current monitors attached... we fall back to the auto-resize option. However, this is kinda complex and hard to test for me, so I have no qualms about accepting this patch as-is. 🙂

For potential downstream testing: screen geometries can also change on some tablet-like devices at runtime. (Turn tablet 90 degrees or open it up to double the screen. There are displays which extend at runtime via a rollup mechanism now too.)
