Don't resize windows when request is rejected by WM. Only use the resize

Browse Source 
Sat Mar 14 00:03:34 1998  Owen Taylor  <owt1@cornell.edu>

	* gtk/gtkwindow.c:
          Don't resize windows when request is rejected by WM.
	  Only use the resize count to guess whether a Configure
	  event was a rejection by the WM, or a move.

	* gdk/gdk.c gdk/gdktypes.h:
	  - Don't XDestroyWindow foreign windows (If they're a child of
	  one of our windows, reparent them to root and send them a WM
	  delete event, otherwise, just delete the GTK structure.)
	  Handle notification of their deletion properly.
          (Made foreign windows a seperate window type to do this)

	* gtk/gtkobject.c (gtk_object_set_data_full):
	  Call the DestroyNotify when replacing the object data.
