al_get_ustr_dimensions
void al_get_ustr_dimensions(const ALLEGRO_FONT *f,
ALLEGRO_USTR const *ustr,
int *bbx, int *bby, int *bbw, int *bbh)
Sometimes, the al_get_ustr_width and al_get_font_line_height functions are not enough for exact text placement, so this function returns some additional information.
