Crap, you're right. Before I started this I checked if Ubuntu had openjpeg2
and they do[1] but it turns out it's really just openjpeg 1.3 (if anyone
knows why they made a separate package named libopenjpeg2 when it's really
openjpeg 1.3, I'd be curious to learn why).

Well that settles it for me, then. I'll keep compatibility with 1.5.
