Extracts a range of characters from a font.
This function extracts a character range from a font and returns a new font
that contains only the range of characters selected by this function. You
can pass -1 for either the lower or upper bound if you want to select all
characters from the start or to the end of the font.
/* Create a font of only capital letters */
capitals = extract_font_range(myfont, 'A', 'Z');
/* Create a copy of the font */
fontcopy = extract_font_range(myfont, -1, -1);
Returns a pointer to the new font or NULL on error. Remember that you are
responsible for destroying the font when you are finished with it to
avoid memory leaks.
