    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.
