Re: Typical to/from EXIF conversions

I've not missed.

I rely only on current official chunks plus eXIf, trying to keep EXIF 
modifications mostly optional in "to PNG" scenario.

As it's not possible to rotate image without modification EXIF - I skip 
this part.

Yes it's possible to add step 6b like "Transform image according to 
Orientation tag and remove it"
