Install boolean child properties "resize" and "shrink".

2003-06-09  Matthias Clasen  <maclas@gmx.de>

	* gtk/gtkpaned.c (gtk_paned_class_init): Install boolean child
	properties "resize" and "shrink".
	(gtk_paned_[gs]et_child_property): Implementations of
	GtkContainer::[gs]et_child_property.
	* tests/testgtk.c (toggle_resize, toggle_shrink): Use the new
	paned child properties instead of remove/add hacks.  (#114667,
	Soeren Sandmann)
