    /**
     * Creates a font registry and initializes its content from
     * a property file.
     * <p>
     * There must be an SWT Display created in the current 
     * thread before calling this method.
     * </p>
     * <p>
     * The OS name (retrieved using <code>System.getProperty("os.name")</code>)
     * is converted to lowercase, purged of whitespace, and appended 
     * as suffix (separated by an underscore <code>'_'</code>) to the given 
     * location string to yield the base name of a resource bundle
     * acceptable to <code>ResourceBundle.getBundle</code>.
     * The standard Java resource bundle mechanism is then used to locate
     * and open the appropriate properties file, taking into account
     * locale specific variations.
     * </p>
     * <p>
     * For example, on the Windows 2000 operating system the location string
     * <code>"com.example.myapp.Fonts"</code> yields the base name 
     * <code>"com.example.myapp.Fonts_windows2000"</code>. For the US English locale,
     * this further elaborates to the resource bundle name
     * <code>"com.example.myapp.Fonts_windows2000_en_us"</code>.
