>   class NodeMoulder : public NodeRenderableInk

    Author:     Mike_Kenny (Xara Group Ltd) <camelotdev@xara.com>
    Created:    1/12/94
    Purpose:    defines the structure of a moulder object. The moulder exists only as a child
                of a mould object, controlling the production and manipulation of moulded 
                versions of associated siblings. ie for each child (C) of a mould object, we 
                create a moulder object (M).
                M controls the actual production and rendering of paths and bitmaps generated
                by C. 
    SeeAlso:    Mould (the parent object)
