(enum window_part): New enumeration.
(Qleft_fringe, Qright_fringe): Replace Qleft_bitmap_area and Qright_bitmap_area. (coordinates_in_window): Return an enumerator from enum window_part. Fix handling of right scroll bar. (Fcoordinates_in_window_p): Doc fix. Return `left-fringe' and `right-fringe' instead of `left-bitmap-area' and `right-bitmap-area'. Use enumerators from enum window_part instead of hard-coded integers. (check_window_containing, window_from_coordinates): Use enumerators from enum window_part instead of hard-coded integers. (syms_of_window): Replace Qleft_bitmap_area and Qright_bitmap_area.with Qleft_fringe and Qright_fringe.
