* gutter.c (output_gutter): add some debug.
* glyphs.h (struct Lisp_Image_Instance): add display_hash.
(IMAGE_INSTANCE_DISPLAY_HASH): new macro.
(XIMAGE_INSTANCE_DISPLAY_HASH): ditto.
* redisplay-output.c (compare_runes): use display_hash to
determine if glyphs really are not the same.
* glyphs.c (update_subwindow): check display_hash to see if
anything really needs to be updated. If not then do
nothing. Record the display_hash after updating.
(image_instance_equal): compare the image_instance face also.
