Re: CALL for DISCUSSION: eXIf 20170115

Well, I think such kind of tool is good as example, but very VERY BAD as 
part of real image processing.

Using pngexif in real image processing encourage users to ignore iCCP, 
gAMA, pHYs and may be even size from IHDR in favour of EXIF data (e.g. 
if user have some tool to parse EXIF).

So I support compression of EXIF not only for saving space, but more for 
'salt' to encourage developers to write software handling all PNG 
metadata, not only EXIF.
