New functions gtk_window_set_transient_for() - set up a "transient for"

	* gtk/gtkwindow.c: New functions
        gtk_window_set_transient_for() - set up a "transient for" relationship.
	gtk_window_set_default_size() - set the initial size of a window
	   distinct from its minimum size.
	gtk_window_set_geometry_hints() - Allow the user to set
	   minimum, maximum sizes, aspect rations, and gridded geometry,
	   possibly all with respect to a subwidget of the window.
	These interfaces are still a wee bit experimental.

	* gdk/gdk.c: Added gdk_window_set_transient_for(),
	gdk_window_set_geometry_hints(), and gdk_window_set_role().

	* gdk/gdktypes.h: Added new types for find-grained specification
	of WM hints.

	* gtk/testgtk.c: Various changes to tests to test the
	above new functions.

	* gtk/gtkfontsel.c: Squash a few 'const' warnings.

	* gtk/gtktogglebutton.c (gtk_toggle_button_realize): Restored
	call to gtk_style_set_background() to prevent egregious
	flashing to black.
