/**
sl@0
    27
Helper class that converts a character code to a glyph code. 
sl@0
    28
To do this requires calling into a font rasterizer from this
sl@0
    29
process, therefore the rasterizer must be loaded in this 
sl@0
    30
process - to do this it must create its own fontstore and load
sl@0
    31
its own instance of a font rasterizer. This class performs 
sl@0
    32
no shaping of characters.
sl@0
    33
sl@0
    34
@note This class and/or its implementation should not be 
sl@0
    35
    copied or used as refernce code - the proper implementation
sl@0
    36
    would not create a new fontstore, but instead either parse the
sl@0
    37
    font table of the associated font itself, or use the
sl@0
    38
    FBS server-side fontstore.
