#477
## Description of change
F11 menu (window settings) did not work for arena model because the game
engine races to create many windows, so our logic of grabbing the first
window created doesn't always get the main window.
## Testing

Fixes#307
## Description of change
Add an option for making TDJ/UFC subscreen window borderless in windowed
mode
Add another option for keeping the subscreen "always on top".
Add size / position arguments to SDVX windowed subscreen, exactly the
same as what is allowed for IIDX.
## Testing
Seems to work....

## 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.
