I'll also add that I don't know how we would implement gco since it is
supposed to return the "current object" which the Matlab docs define
as "the last object clicked on, excluding uimenus".  With the gnuplot
backend, we don't get any information back about any mouse events that
happen in the figure window, so I don't see what we would return.  I
assume that we can eventually make this function work for the
OpenGL-based backend.
