* This method is provided for internal and exclusive use by Swing.
*
* It may be used in conjunction with fontSupportsDefaultEncoding(Font)
* In the event that a desktop properties font doesn't directly
* support the default encoding, (ie because the host OS supports
* adding support for the current locale automatically for native apps),
* then Swing calls this method to get a font which uses the specified
* font for the code points it covers, but also supports this locale
* just as the standard composite fonts do.
* Note: this will over-ride any setting where an application
* specifies it prefers locale specific composite fonts.
* The logic for this, is that this method is used only where the user or
* application has specified that the native L&F be used, and that
* we should honour that request to use the same font as native apps use.
*
* The behaviour of this method is to construct a new composite
* Font object that uses the specified physical font as its first
* component, and adds all the components of "dialog" as fall back
* components.
* The method currently assumes that only the size and style attributes
* are set on the specified font. It doesn't copy the font transform or
* other attributes because they aren't set on a font created from
* the desktop. This will need to be fixed if use is broadened.
*
* Operations such as Font.deriveFont will work properly on the
* font returned by this method for deriving a different point size.
* Additionally it tries to support a different style by calling
* getNewComposite() below. That also supports replacing slot zero
* with a different physical font but that is expected to be "rare".
* Deriving with a different style is needed because its been shown
* that some applications try to do this for Swing FontUIResources.
* Also operations such as new Font(font.getFontName(..), Font.PLAIN, 14);
* will NOT yield the same result, as the new underlying CompositeFont
* cannot be "looked up" in the font registry.
* This returns a FontUIResource as that is the Font sub-class needed
* by Swing.
* Suggested usage is something like :
* FontUIResource fuir;
* Font desktopFont = getDesktopFont(..);
* // NOTE even if fontSupportsDefaultEncoding returns true because
* // you get Tahoma and are running in an English locale, you may
* // still want to just call getCompositeFontUIResource() anyway
* // as only then will you get fallback fonts - eg for CJK.

* Otherwise, we register all the paths on Solaris, because
* the fontPath we have here is the complete one from
* parsing /var/sadm/install/contents, not just
* what's on the X font path (may be this should be
* changed).
* But for now what it means is that if we didn't do
* this then if the font weren't listed anywhere on the
* less complete font path we'd trigger loadFonts which
* actually registers the fonts. This may actually be
* the right thing tho' since that would also set up
* the X font path without which we wouldn't be able to
* display some "native" fonts.
* So something to revisit is that probably fontPath
* here ought to be only the X font path + jre font dir.
* loadFonts should have a separate native call to
* get the rest of the platform font path.
*
* Registering the directories can now be avoided in the
* font configuration initialisation when filename entries
* exist in the font configuration file for all fonts.
* (Perhaps a little confusingly a filename entry is
* actually keyed using the XLFD used in the font entries,
* and it maps *to* a real filename).
* In the event any are missing, registration of all
* directories will be invoked to find the real files.
*
* But registering the directory performed other
* functions such as filling in the map of all native names
* for the font. So when this method isn't invoked, they still
* must be found. This is mitigated by getNativeNames now
* being able to return at least the platform name, but mostly
* by ensuring that when a filename key is found, that
* xlfd key is stored as one of the set of platform names
* for the font. Its a set because typical font configuration
* files reference the same CJK font files using multiple
* X11 encodings. For the code that adds this to the map
* see X11GE.getFileNameFromPlatformName(..)
* If you don't get all of these then some code points may
* not use the Xserver, and will not get the PCF bitmaps
* that are available for some point sizes.
* So, in the event that there is such a problem,
* unconditionally making this call may be necessary, at
