## Description of change
Adds a new option to forcibly set the full screen resolution.
Same idea as -windowscale.
## Compiling
🔺
## Testing
Seems to be showing similar results as -windowscale:
* Works GREAT for IIDX/SDVX
* popn launches at correct resolution but only draws a small image (at
native res) - can be scaled with F11 menu
* nostalgia is broken in weird ways, image is drawn correctly but bottom
`credits` text draws at wrong offset, game's wintouch logic broken
(perhaps expectedly)
## Other notes
In theory this could enable "play sdvx in landscape mode" option but the
image scaling doesn't quite work with extreme values.
