| * 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 |

| // So for the purposes of font configuration logical fonts where AWT |
| // heavyweights need to access the font via X APIs we need to ensure that |
| // the directory for precisely the encodings needed by this are added to |
| // the x font path. This requires that we note the platform names |
| // specified in font configuration files and use that to identify the |
| // X font directory that contains a font.dir file for that platform name |
| // and add it to the X font path (if display is local) |
| // Here we make use of an already built map of xlfds to font locations |
| // to add the font location to the set of those required to build the |
| // x font path needed by AWT. |
| // These are added to the x font path later. |
| // All this is necessary because on Solaris the font.dir directories |
| // may contain not real font files, but symbolic links to the actual |
| // location but that location is not suitable for the x font path, since |
| // it probably doesn't have a font.dir at all and certainly not one |
| // with the required encodings |
| // If the fontconfiguration file is properly set up so that all fonts |
| // are mapped to files then we will never trigger initialising |
| // xFontDirsMap (it will be null). In this case the awtfontpath entries |
| // must specify all the X11 directories needed by AWT. |
