The letters j, y, p, and g get cut off when in fit window to text mode! Help!
Okay, there seems to be no way I can anticipate every single font and font size combination, and apparently the Bitmap class is really bad at telling size. So, if you're having this problem, you're going to have to fix it yourself. Find these lines (there will be two):
height += delta + (delta * 0.2).to_i
And play with the 0.2 until it works for whatever font/font size you're using.
