+       Attempt to make redisplay more selective when changing fonts.
+       * frame.h (struct frame): New bitfield fonts_changed.
+       * dispextern.h (fonts_changed_p, adjust_glyphs): Remove declaration.
+       (adjust_frame_glyphs): Add prototype.
+       * dispnew.c (fonts_changed_p): Remove.
+       (adjust_glyphs): Remove becase we do not
+       adjust matrices on all frames at once any more.
+       (adjust_frame_glyphs): Block and unblock input here.
+       (adjust_glyph_matrix): Use fonts_changed.
+       (change_frame_size_1): Use adjust_frame_glyphs.
+       * font.c (font_open_entity): Use fonts_changed.
+       * frame.c (set_menu_bar_lines, Fmake_terminal_frame):
+       * w32fns.c (x_set_menu_bar_lines, x_set_tool_bar_lines, Fx_show_tip):
+       * window.c (Fdelete_other_windows_internal, Fwindow_resize_apply)
+       (Fsplit_window_internal, Fdelete_window_internal, grow_mini_window)
+       (shrink_mini_window, Fresize_mini_window_internal)
+       (window_scroll_pixel_based, Fset_window_configuration)
+       (apply_window_adjustment, Fset_window_vscroll):
+       * xfns.c (x_set_menu_bar_lines, x_set_tool_bar_lines, Fx_show_tip):
+       Use adjust_frame_glyphs.
+       * xdisp.c (redisplay_tool_bar, redisplay_window, try_window)
+       (try_window_reusing_current_matrix, try_window_id, display_line)
+       (IT_EXPAND_MATRIX_WIDTH): Use fonts_changed.
+       (redisplay_internal): Consider fonts_changed and adjust frame
+       matrices for each frame only if the frame is visible.  If font
+       has been changed on some frame during full redisplay, retry
+       only visible frames where the font has been actually changed.
