| * 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 |
