Noel Grandin 3b83c6ac80 make BufferedDecompositionPrimitive2D store a Primitive2DReference..
.. instead of a Primitive2DContainer.

The container very frequently contains only a single item, since
the decomposition method often sticks only a single top-level node
in there, so it turns out to be a net loss overall, memory
consumption-wise.

Also, if we return a single Primitive2DReference from
a BufferedDecomposition, that maximises the sharing of
data between the BufferedDecomposition objects at the
bottom of the decomposed tree, and objects higher up.
