draw_focus, draw_default

[Havoc Pennington <hp redhat com>]

Hi,

Just to be sure there are no objections, I'm about to fix the bug
about draw_focus and draw_default. Basically: these virtual functions
will be removed from GtkWidget, and the wrappers
(gtk_widget_draw_focus()) will also go away. Then all widgets will be
hacked to just draw focused or unfocused in expose_event, and calls to
draw_focus() will be replaced by a simple queue_draw().

This should make it less confusing to write new widgets from scratch,
since these methods don't make any sense.
