Another important issue is the specification of a clear interface for the
backend plotting engines.  This could be implemented as a C++ class
allowing for additions in the future.  The current plotting
implementation requires changing loads of __pl*__.m files, which were
originally written for gnuplot.  This is what the PLplot and graceplot
interfaces do right now. This ought to be changed in the future.

As soon as the interface is clearly defined and becomes "the" standard, I
think that people working with the different plotting engines will be
more motivated to implement the backends.
