* If a font configuration file has specified a baseFontPath

* 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
* some cost to JRE start-up
