However, pygame.font does expose a number of metrics (ascent, descent, max height, line spacing and sizing info and advance for individual characters) about the rendered font that can be used to figure out how to work with a font in a large number of cases, regardless of the point size argument used in the font's constructor. In fact, the point size of the font may not actually relate to anything about the font's rendered pixel size (that's really up to the font designed, who's allowed to design "outside the box" in a number of ways), so the point size itself can be misleading in determining positioning choices depending on the individual ttf used. So Luca, what are you trying to do with the font object passed in, in your library? In what way do you expect the font point size passed into the constructor to the Font object to help you with that task?
