Fonts

It is possible to create, replace, and delete fonts during the game using the following functions. (Don't replace a font that is set as the current font or at least set it again afterwards.)

font_add(name, size, bold, italic, first, last) Adds a new font and returns its index, indicating the name, size, whether it is bold or italic, and the first and last character that must be created.
font_add_sprite(spr, first, prop, sep) Adds a new font and returns its index. The font is created from a sprite. The sprite should contain a subimage for each character. first indicate the index of the first character in the sprite. For example, use ord('0') if your sprite only contains the digits. prop indicates whether the font is proportional. In a proportional font, for each character the width of the bounding box is used as the character width. Finally, sep indicates the amount of white space that must separate the characters horizontally. A typical value would lie between 2 and 8 depending on the font size.
font_replace(ind, name, size, bold, italic, first, last) Replaces the font ind with a new font, indicating the name, size, whether it is bold or italic, and the first and last character that must be created.
font_replace_sprite(ind, spr, first, prop, sep) Replaces the font ind with a new sprite-based font.
font_delete(ind) Deletes the font with the given index, freeing the memory it uses.
