Add "Experimental 4:3 Aspect Ratio" option

[drojf]

This adds an option which runs the game in 4:3 resolution for use on monitors with 4:3 resolution (or less than 16:9 aspect)

Warped Spiral Mask

• One episodes 5 and up, Sprial fade and other effects are squished more than they should be - these may be better cropped or use the original 4:3 version (but probably can't replace the file directly as non-4:3 OG mode uses these files as well?)

After some investigation:
for the question arcs (or at least episode 1), we have stretched all the masks, so the normal mod spiral mask looks like this:

But for the answer arcs, the same spiral mask is cropped, and looks like this:

So the engine actually behaves the same, it's just the actual mask image is different

so for question arcs it works out because the image is stretched and then un-stretched, but for the answer arcs it doesn't work

because it is is cropped and then un-stretched

Here is the unmodded game's spiral:

this does mean our normal modded game is warped for the question arcs, and furthermore it's not consistent between question and answer arcs

Here is a pack containing all the OG masks (some are created from modded masks if no OG exists):
