I am having an issue with orxFontGen setting the size of a character, but making the character itself too small and the rest being padding even though 0 is specified.
Using a mono font I get the following result with these parameters:
-t char.txt -s 40 --font "d.ttf" -o fontout -m -p 0
Which is technically correct. The dimensions between one character an the next is 40 pixels, but I have no padding, yet there is padding.
