+       * dispextern.h (struct glyph_string): Rename member for_overlaps_p
+       to for_overlaps.  Now occupy 3 bits.
+       (OVERLAPS_PRED, OVERLAPS_SUCC, OVERLAPS_BOTH)
+       (OVERLAPS_ERASED_CURSOR): New defines.
+       (struct redisplay_interface): Add new OVERLAPS arg to member
+       fix_overlapping_area.
+       (x_fix_overlapping_area): Add new OVERLAPS arg.
+       (get_glyph_string_clip_rects): Add extern.
+
+       * dispnew.c (redraw_overlapping_rows): Call
+       rif->fix_overlapping_area with new OVERLAPS arg as redrawn part.
+
+       * xdisp.c: Rename member for_overlaps_p in struct glyph_string to
+       for_overlaps.
+       (get_glyph_string_clip_rects): New function created from
+       get_glyph_string_clip_rect.  Set clipping rectangles according to
+       the value of for_overlaps.  Enable to store multiple clipping
+       rectangles.
+       (get_glyph_string_clip_rect): Use get_glyph_string_clip_rects.
+       (fill_composite_glyph_string, fill_glyph_string, draw_glyphs):
+       Rename argument OVERLAPS_P to OVERLAPS.  All uses in macros changed.
+       (x_fix_overlapping_area): Add OVERLAPS arg.  Pass it to draw_glyphs.
+       (draw_phys_cursor_glyph): Set width of erased cursor to use it for
+       calculating clipping rectangles later.  Call
+       x_fix_overlapping_area with new OVERLAPS arg to draw only erased
+       cursor area.
+       (expose_overlaps): Call x_fix_overlapping_area with new
+       OVERLAPS arg to draw overlaps in both preceding and succeeding rows.
+
+       * xterm.c, w32term.c, macterm.c: Rename member for_overlaps_p in
+       struct glyph_string to for_overlaps.
