 * face:            A bopti_image_t of the face of the person who's saying this
 *                  text. This bopti_image_t should have a width of F_WIDTH and
 *                  a height of F_HEIGHT.
 * text:            The text to display.
 * call_before_end: A function called when the end of the text was displayed and
 *                  the user pressed EXE (or wait_continue was true). His
 *                  parameter game is the game struct passed to showtext_opt,
 *                  and i is the current position in text.
 * start_anim:      A boolean, that, if he's true, makes that a little animation
 *                  is shown at the start of showtext_opt.
 * end_anim:        A boolean, that, if he's true, makes that a little animation
 *                  is shown at the end of showtext_opt.
 * for_each_screen: A function called before a page of the dialog gets drawn.
 *                  His parameter game is the game struct passed to
 *                  showtext_opt, and i is the current position in text.
 * line_duration:   How many ms showtext_opt will wait after a line has been
 *                  drawn.
 * update_screen:   When he's true showtext_opt will update the screen after
 *                  drawing a line etc.
 * start_i:         At which position I start displaying the text.
 * wait_continue:   If I should wait that EXE is pressed after drawing a page.
