2777      * in one place, here, since otherwise the implementation is spread
2778      * around it may be difficult to track.
2779      * The methods below call into SunGraphicsEnvironment which creates a
2780      * new FontConfiguration instance. The FontConfiguration class,
2781      * and its platform sub-classes are updated to take parameters requesting
2782      * these behaviours. This is then used to create new composite font
2783      * instances. Since this calls the initCompositeFont method in
2784      * SunGraphicsEnvironment it performs the same initialization as is
2785      * performed normally. There may be some duplication of effort, but
2786      * that code is already written to be able to perform properly if called
2787      * to duplicate work. The main difference is that if we detect we are
2788      * running in an applet/browser/Java plugin environment these new fonts
2789      * are not placed in the "default" maps but into an AppContext instance.
2790      * The font lookup mechanism in java.awt.Font.getFont2D() is also updated
2791      * so that look-up for composite fonts will in that case always
2792      * do a lookup rather than returning a cached result.
2793      * This is inefficient but necessary else singleton java.awt.Font
2794      * instances would not retrieve the correct Font2D for the appcontext.
2795      * sun.font.FontManager.findFont2D is also updated to that it uses
2796      * a name map cache specific to that appcontext.
2797      *
2798      * Getting an AppContext is expensive, so there is a global variable
2799      * that records whether these methods have ever been called and can
2800      * avoid the expense for almost all applications. Once the correct
2801      * CompositeFont is associated with the Font, everything should work
2802      * through existing mechanisms.
2803      * A special case is that GraphicsEnvironment.getAllFonts() must
2804      * return an AppContext specific list.
2805      *
2806      * Calling the methods below is "heavyweight" but it is expected that
2807      * these methods will be called very rarely.
2808      *
2809      * If _usingPerAppContextComposites is true, we are in "applet"
2810      * (eg browser) enviroment and at least one context has selected
2811      * an alternate composite font behaviour.
2812      * If _usingAlternateComposites is true, we are not in an "applet"
2813      * environment and the (single) application has selected
2814      * an alternate composite font behaviour.
2815      *
2816      * - Printing: The implementation delegates logical fonts to an AWT
2817      * mechanism which cannot use these alternate configurations.
2818      * We can detect that alternate fonts are in use and back-off to 2D, but
2819      * that uses outlines. Much of this can be fixed with additional work
2820      * but that may have to wait. The results should be correct, just not
