Abstract:

   Watermark font definition. The CWatermarkFont class is responsible
   for managing the font resource for a text watermark. This implements
   the IResWriter interface so that the font can be added to the resource
   cache.

Known Issues:

    The watermark font does not yet use the Uniscript interface to retrieve glyph
    indices.
