Well, the main problem is that neither libtiff nor libpng do support
transformations themselves. This would mean that one would need to read the
files into a bitmap, write a transform function which acts uppon bitmaps and
then write back the bitmaps to their respective formats, right?
Couldn't we rather check if the files are != 16bit and fall back to ImageMagick
in case they are?
