Continue working on display of R2L glyph rows. Reverse glyphs in term.c:append_glyph rather than in extend_face_to_end_of_line. Fix bidi iteration near BEGV and ZV. dispextern.h (struct glyph): New members resolved_level and bidi_type. xdisp.c (append_glyph, append_composite_glyph) (produce_image_glyph, append_stretch_glyph): Set them. term.c (append_glyph): Ditto. xdisp.c (display_line, next_element_from_buffer): Set the glyph row's reversed_p flag if the paragraph base direction is odd. (extend_face_to_end_of_line): Don't reverse the glyphs here. term.c (append_glyph): Reverse glyphs here. bidi.c (bidi_get_next_char_visually): Don't exit early when at ZV. (bidi_paragraph_init): Don't step over a newline if at BEGV. (bidi_paragraph_init): Handle empty buffers.
