I think it would be much better to implement a Matlab-compatible
legend function.  I think doing that is possible now.  The legend
shouuld create an additional axes object that includes three objects
for each entry in the legend.  The first is for the marker associated
with the legend item, the second is for the line, and the third is the
label.  I think placement and sizing will require some effort.  It
would also be nice if the legend object could be opaque so it may
appear on top of other plot objects, but I don't think that is
absolutely necessary.
