I don't think you have to view it that way. A hggroup object is just
the grouping
of other objects. When rendering a hggroup, you just have to recursively
render the children. The actual type of the hggroup is not relevant when
rendering, because the operation is passed to the children. The only things
that you need to render are the core objects; all others are just combination
of these core objects.
