* gtk/gtkstyle.[ch] (_gtk_get_insertion_cursor_gc):
Centralize lookup and caching of cursor GC's here.
* gtk/gtkentry.[ch] gtk/gtktextview.[ch] gtk/gtktextdisplay.c
gtk/gtklabel.c: Move to using _gtk_get_insertion_cursor_gc().
* gtk/gtkentry.c (gtk_entry_expose): Draw cursors
under the text, not over the text.
* gtk/gtkwidget.c (gtk_widget_class_init): add
a secondary-cursor-color property.
* gtk/gtkwidget.c (gtk_widget_class_init): Decrease
the default aspect ratio to 1/25 (0.04).
* tests/testgtkrc (bell_duration): Comment out
cursor color setting.
