* using glyphs may lead to lower quality display. Probably number
* of glyphs is the ideal, but filesize is information we already
* have and is good enough for the known cases.
* Also don't want to register fonts that match JRE font families
* but are coming from a source other than the JRE.
* This will ensure that we will algorithmically style the JRE
* plain font and get the same set of glyphs for all styles.

* if it returns the same object as its argument that means this
* font was newly registered.

* that corresponded to the "install" locale for windows.
* Since we are in this code block because there are unmapped

* and then open the files to read the names. We don't generally
* want to open font files, as its a performance hit, but this
* occurs only for a small number of fonts on specific system
* configs - ie is believed that a "true" Japanese windows would
* have JA names in the registry too.
* Clone fontToFileMap and remove from the clone all keys which
* match a fontToFamilyNameMap key. What remains maps to the
* files we want to open to find the fonts GDI returned.
* A font in such a file is added to the fontToFileMap after
* checking its one of the unmappedFontNames we are looking for.
* The original name that didn't map is removed from fontToFileMap
* so essentially this "fixes up" fontToFileMap to use the same
* name as GDI.
* Also note that typically the fonts for which this occurs in
* CJK locales are TTC fonts and not all fonts in a TTC may have
* localised names. Eg MSGOTHIC.TTC contains 3 fonts and one of
* them "MS UI Gothic" has no JA name whereas the other two do.
* So not every font in these files is unmapped or new.

* The methods below call into SunGraphicsEnvironment which creates a
* new FontConfiguration instance. The FontConfiguration class,
* and its platform sub-classes are updated to take parameters requesting
* these behaviours. This is then used to create new composite font
* instances. Since this calls the initCompositeFont method in
* SunGraphicsEnvironment it performs the same initialization as is
* performed normally. There may be some duplication of effort, but
* that code is already written to be able to perform properly if called
* to duplicate work. The main difference is that if we detect we are
* running in an applet/browser/Java plugin environment these new fonts
* are not placed in the "default" maps but into an AppContext instance.
* The font lookup mechanism in java.awt.Font.getFont2D() is also updated
* so that look-up for composite fonts will in that case always
* do a lookup rather than returning a cached result.
* This is inefficient but necessary else singleton java.awt.Font
* instances would not retrieve the correct Font2D for the appcontext.
* sun.font.FontManager.findFont2D is also updated to that it uses
* a name map cache specific to that appcontext.
*
* Getting an AppContext is expensive, so there is a global variable
* that records whether these methods have ever been called and can
* avoid the expense for almost all applications. Once the correct
* CompositeFont is associated with the Font, everything should work
* through existing mechanisms.
* A special case is that GraphicsEnvironment.getAllFonts() must
