This is the basic primitive for representing a text portion. It contains
all needed information. If it is not handled by a renderer, it's decomposition
will provide the text PolyPolygon outlines as filled polygons, correctly
transformed.
To get better text quality, it is suggested to handle tis primitive directly
in a renderer. In that case, e.g. hintings on the system can be supported.
