  62 The recursive Hilbert space-filling curve, both 2D and 3D variants.
  63 It incrementally animates the growth and recursion to the maximum
  64 depth, then unwinds it back.
  65
  66 The Hilbert path is a single contiguous line that can fill a volume
  67 without crossing itself.  As a data structure, Hilbert paths are
  68 useful because ordering along the curve preserves locality: points
  69 that are close together along the curve are also close together in space.
  70 The converse is often, but not always, true.  The coloration
  71 reflects this.
