575 * actually registers the fonts. This may actually be
576 * the right thing tho' since that would also set up
577 * the X font path without which we wouldn't be able to
578 * display some "native" fonts.
579 * So something to revisit is that probably fontPath
580 * here ought to be only the X font path + jre font dir.
581 * loadFonts should have a separate native call to
582 * get the rest of the platform font path.
583 *
584 * Registering the directories can now be avoided in the
585 * font configuration initialisation when filename entries
586 * exist in the font configuration file for all fonts.
587 * (Perhaps a little confusingly a filename entry is
588 * actually keyed using the XLFD used in the font entries,
589 * and it maps *to* a real filename).
590 * In the event any are missing, registration of all
591 * directories will be invoked to find the real files.
592 *
593 * But registering the directory performed other
594 * functions such as filling in the map of all native names
595 * for the font. So when this method isn't invoked, they still
596 * must be found. This is mitigated by getNativeNames now
597 * being able to return at least the platform name, but mostly
598 * by ensuring that when a filename key is found, that
599 * xlfd key is stored as one of the set of platform names
600 * for the font. Its a set because typical font configuration
601 * files reference the same CJK font files using multiple
602 * X11 encodings. For the code that adds this to the map
603 * see X11GE.getFileNameFromPlatformName(..)
604 * If you don't get all of these then some code points may
605 * not use the Xserver, and will not get the PCF bitmaps
606 * that are available for some point sizes.
607 * So, in the event that there is such a problem,
608 * unconditionally making this call may be necessary, at
609 * some cost to JRE start-up
