* FTLibrary class is the global accessor for the Freetype library.

* All constructors are private therefore clients cannot create or
* instantiate this class themselves and must access it's methods via the
* 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>
