Is there a work-around for this problem?  I would like to use the
Cairo output drivers to generate a series of plots, but this problem
is preventing me from doing so.

I see that the example plots on the web site are made with using
family files.  I would like to be able to use arbitrary file names for
each plot in this sequence, not just "foo-1.png" then "foo-2.png" etc.
 Is there a way to do this without using plend between plots?

Thank you for your time,
