    27 Helper class that converts a character code to a glyph code. 
    28 To do this requires calling into a font rasterizer from this
    29 process, therefore the rasterizer must be loaded in this 
    30 process - to do this it must create its own fontstore and load
    31 its own instance of a font rasterizer. This class performs 
    32 no shaping of characters.
    33 
    34 @note This class and/or its implementation should not be 
    35     copied or used as refernce code - the proper implementation
    36     would not create a new fontstore, but instead either parse the
    37     font table of the associated font itself, or use the
    38     FBS server-side fontstore.
