Running an external JBIG2 encoder if one exists

[Sean Whitton <spwhitton@spwhitton.name>]

Hello,

An upcoming release of OCRmyPDF, which I maintain in Debian, will call
jbig2 if it can be found on PATH, or gracefully degrade.  On Debian,
this won't do anything, since we don't have that package.

I don't have any trained intuitions about patent law, but I assume that
the fact that OCRmyPDF contains code that looks for a jbig2 executable
is not any kind of patent violation?

I note that the US patents on jbig2 encoding have expired.

Please CC me.
