+        Optimize glyph row clearing and copying routines.
+        * dispextern.h (struct glyph_row): Change layout of struct
+        glyph_row to help copy_row_except_pointers.  Adjust comment.
+        * dispnew.c (null_row): Remove.
+        (clear_glyph_row): Use offsetof and memset to find and clear
+        just the members that need clearing.  Adjust comment.
+        (copy_row_except_pointers): Likewise for copying.
