I think what Richard was asking is whether the "cairo drawing
context" struct, or "cairo_t", that is used internally by gnuplot
could somehow be exposed programmatically.  But I don't see how
this could be done -- seems to me it would require building
gnuplot as a library, not a stand-alone executable.
