Detailed Description

ShadowPrimitive2D class.

    This primitive defines a generic shadow geometry construction
    for 2D objects. It decomposes to a TransformPrimitive2D embedded
    into a ModifiedColorPrimitive2D.

    It's for primitive usage convenience, so that not everyone has
    to implement the generic shadow construction by himself.

    The same geometry as sequence of primitives is used as geometry and
    as shadow. Since these are RefCounted Uno-Api objects, no extra objects
    are needed for the shadow itself; all the local decompositions of the
    original geometry can be reused from the renderer for shadow visualisation.
