Better scaling support

[github-actions]

Description

Better resolution scaling with multiple options.

Supports scale offsets.
Current modes available : stretch to fit, simple letterboxing using floats or integers.

How to use the extension

Different actions, conditions and expressions for current scaling mode and offset

Scaling mode is self-explanatory, it changes how the screen is scaled.

Scaling offset is subtracted from the target scale behind the scenes, it's used when you want the screen to appear smaller. ( Some resolutions appear too big on screen, which looks weird, like the GameBoy's resolution ( 160x144 ) )

Scaling factor is a multiplier to the size of the window, it can be set independently or when fullscreening.
