Owen Taylor f903bdf1a7 Fix a reference to window_private->destroyed.
Sun Oct  3 18:13:44 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkwidget.c (gtk_reset_shapes_recurse):
	Fix a reference to window_private->destroyed.

	* gtk/gtkplug.c (gtk_plug_realize): Fix up a direct
	(ugly) setting of an internal GdkWindow member to use
	a _slightly_ cleaner macro.

	* gdk/gdkprivate.h: Split GdkWindowPrivate into
	GdkDrawablePrivate and GdkWindowPrivate.
	Add extra macros for accessing GDK_DRAWABLE_ components.

	* *.[ch]: Massive adjustments for the above, use the
	new macros in a lot of places.
