Title: TIFF - clarify comments, enable float predictor

Mostly this is just adding clarifying comments, not much review needed of that.

The only real change is enabling the PREDICTOR_FLOATINGPOINT. This has been around for a few years now, so I think it's probably safe to enable it. So few apps reliably read float tiff at all, I think it's probably safe to assume that those which do are modern enough to also be ok with the newer predictor. In improves compression a bit.

If this backfires and gives people problems, let me know and I'll disable it again.
