looks good to me now, except one thing I'm not sure about, as I'm not 
that deep in the inner structure of the core.

Is the t3lib_div::imageMagicCommand method called for every image 
processing/generation in typo3? If so, there has to be a way to disable 
the stripping from within TS, because there are usecases where you might 
need to render the file with all profiles / EXIF data etc. (like in some 
galleries where you provide downloads in different resolutions or 
something like that).
