+ * static <code>FTLibrary::Instance()</code> function.
+ *
+ * Just because this class returns a valid <code>FTLibrary</code> object
+ * doesn't mean that the Freetype Library has been successfully initialised.
+ * Clients should check for errors. You can initialse the library AND check
+ * for errors using the following code...
+ * <code>err = FTLibrary::Instance().Error();</code>
