I'd prefer to determine if the desired device is supported by the local gnuplot, and if not try "convert".

In the event we cannot determine if gnuplot supports a devices (pdf in this instance) I think we need to be certain that "convert" does, and that convert present, before making this change.

How can we determine if "convert.exe" exists for Windows?
