Owen Taylor c848fbbcfe Centralize lookup and caching of cursor GC's here. 
Sun Mar  3 14:26:33 2002  Owen Taylor  <otaylor@redhat.com>

        * 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.
