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

|
*
|
||
|
|
* This class encapsulates the Freetype Library. This is a singleton class
|
||
|
|
* and ensures that only one FT_Library is in existence at any one time.
|
||
|
|
* 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>
