// First, the blacklist. We list font families that can crash Tux Paint
// via bugs in the SDL_ttf library. We also test fonts to be sure that
// they have both uppercase and lowercase letters. Note that we do not
// test for "Aa", because it is OK if uppercase and lowercase are the
// same. (but not nice -- such fonts get a low score later)
//
// We test the alphabet twice, to help with translation. If the users
// will be unable to type ASCII letters, then both lines should be
// translated. Otherwise, only Line X should be translated and the
// ASCII-only fonts should be given bad scores in the scoring code below.
