Class for specifying a single typeface element within a linked typeface specification.

Its features determine how the typeface is rendered within the linked fonts that use it.

This class is used to communicate between the server and the rasterizer.

Another similar but separate class, CLinkedTypefaceElementSpec, will be used client side

and to communicate between the server and the rasterizer.

WARNING: Class for internal and partner use ONLY.  Compatibility is not guaranteed in future releases.
