/**

Helper class that converts a character code to a glyph code. 

To do this requires calling into a font rasterizer from this

process, therefore the rasterizer must be loaded in this 

process - to do this it must create its own fontstore and load

its own instance of a font rasterizer. This class performs 

no shaping of characters.

@note This class and/or its implementation should not be 

    copied or used as refernce code - the proper implementation

    would not create a new fontstore, but instead either parse the

    font table of the associated font itself, or use the

    FBS server-side fontstore.
