Remove use of libunicode in favor of new GLib functions.

Wed Jun 21 11:41:43 2000  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkentry.c gtk/gtkimcontextsimple.c gtk/gtklabel.c
	gtk/gtktexttypes.c gtk/testtext.c modules/linux-fb/basic.c:
	Remove use of libunicode in favor of new GLib functions.

	* gtk/gtkcolorsel.c: Remove conditional includes for FB, win32,
	nano-x, framebuffer. The X11 include is just a hack until we get
	the necessary functions in gdkcolor.h, so there is no reason to
	add other includes of platforms.

	* gtk/gtkwindow.c (gtk_window_compute_default_size): Revert
	window bigger than the screen change.

        * gtk/testgtk.c: Revert some random changes from Elliot
	that had no particular point and were causing testgtkrc
	not to function correctly.

	* gdk/gdkregion-generic.h: Revert change from Elliot. Just
	because GdkSegment and GdkRegionBox have the same fields,
	it doesn't mean that 'typedef GdkSegment GdkRegionBox'
	results in clearer code.

	* gdk/x11/gdkinput-x11.c (gdk_input_common_select_events,
	gdk_input_translate_coordinates): Fix missed GdkObjectification
