Compare with previous version

I tested this MR in a local build with !655 (merged) modiifcations and I can load a 2.2 Gb JP2 file, and then navigate in the image very smoothly. It may be a bit faster to load than with previous version of OpenJPEG, but that's hard to say on a single test.

Maybe we should test on W10 platform, but on Ubuntu 18.04, it's fine.
