Okay, this will be a bit complicated to explain. While I was trying to figure out how image sprite editing and replacement works, I've noticed that there was a serious inconsistency in th14 and th14.3 when running in 960x720 - namely that glyphs from the main font in Ascii.png are not positioned on the same vertical baseline, to the point that some get clipped. (bottom screenshot)
I played around with the file and was able to fix this (middle centre screenshot) by moving the 2nd and 3rd row up and the 5th row down, I also moved only the ^ on the 4th row down, because it was getting clipped. (Final modified PNG is in the middle right). However, when I tried to remove the characters on the 4th row that I hadn't modified, to reduce the image size, something weird happened. Clipping artefacts (middle left screenshot) started to appear near them, even though they weren't there when thcrap was replacing those sprites with identical ones. I have no idea how that is possible, but regardless, there should probably be some kind of alignment fix included in script_latin in the future.
On a related note, as part of the translation I'm doing, I also modified the images (top row PNGs) to change every instance of the decimal mark (framerate display, spell timer, power value and bonus multiplier) from a dot to a comma and got rid of the thousands separator comma from the score display (by putting a single semi-transparent pixel in its box), as is the standard in most of Europe. Now, I'm no artist, so these may look quite ugly, and I don't know if anyone else will care about decimal marks, and I don't feel like figuring out how to work with Github for something that minor, but I'll leave the images here in case you think the idea has any merit.
