Andreas, this is interesting info. This means that our current getExif
implementation is not lossless and not reversible.

- what you suggest is storing ExifData, IptcData, XmpData directly? This is
your intended workflow?
- these classes use std::vector internally, which means copying is always a
deep copy? (We would have to write a wrapper for Qt-style shallow copies)
- should ExifParser::encode be used for JPEGs only when you say it removes
certain tags?
- there are two ExifParser::encode methods. One has docs and says it does not
do unintrusive writing, suggesting the other method. The other has no docs and
requires a byte* buffer. Should this method be of any interest to us?
