   For a cube, the only governing parameter (0) is the cube's edge length.

   For a rectangular prism there are three governing parameters.  The local x-axis is the RPs length (0).
   The local y-axis is the RPs width (1).  The local z-axis is the RPs depth (2).

   For a sphere, the only governing parameter (0) is the sphere's radius.

   For a cylinder there are two governing parameters.  The radius (0), and the height (2).
   The default orientation of a cylinder is along it's z-axis. (double check this)

   For lines, a std::vector of Aftr::Vectors defines the geometry. There must be an even number
   of Aftr::Vectors in the input geometry. The line segments are drawn in the same order as their
   place in the input std::vector. The input std::vector< Vector >* is NOT OWNED by this instance and
   is NOT MODIFIED by this instance; an internal copy in a graphical format is made for efficient rendering.

   For lines, a std::vector of Aftr::aftrColor4ub defines the color at each vertex. The size of
   colors must match the size of lines; that is (lines->size() == colors->size()) evaluates to true.
