Make the GdkScreen font options api public, and add properties

2005-08-26  Matthias Clasen  <mclasen@redhat.com>

	* gdk/gdk.symbols:
	* gdk/gdkscreen.h:
	* gdk/gdkscreen.c: Make the GdkScreen font options api
	public, and add properties GdkScreen::font-options and
	GdkScreen::resolution.  (#314004)

	* gdk/gdkpango.c:
	* gtk/gtksettings.c:
	* gtk/gtkwidget.c: Adjust all callers.

	* gdk/gdkintl.h: Simplify and use glib/gi18n-lib.h.
	* gdk/gdkpango.c: Include gdkintl.h, not gtkintl.h.
	* gdk/gdkscreen.c: Include gdkintl.h.
