	* gdk/x11/gdkselection-x11.c (gdk_utf8_to_compound_text): Fix
	problem with using result of g_get_charset() backwards -
	pointed out by Mikael Hermansson <mikeh@bahnhof.se>.

	* gtk/gtkwindow.c (gtk_window_compute_hints): Support
	negative min_width/height and max_width/height to
	mean "requisition"; this allows setting a window
	to be user-resizable in only one direction easily.

	* gtk/testgtk.c (create_main_window): Remove hard-coded
	usize - set a default size in the vertical direction.
