sl@0: Helper class that converts a character code to a glyph code. 
sl@0: To do this requires calling into a font rasterizer from this
sl@0: process, therefore the rasterizer must be loaded in this 
sl@0: process - to do this it must create its own fontstore and load
sl@0: its own instance of a font rasterizer. This class performs 
sl@0: no shaping of characters.
sl@0: 
sl@0: @note This class and/or its implementation should not be 
sl@0:     copied or used as refernce code - the proper implementation
sl@0:     would not create a new fontstore, but instead either parse the
sl@0:     font table of the associated font itself, or use the
sl@0:     FBS server-side fontstore.
