+/**
+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.
