/**
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.
