Except that PNG is by far not sufficient in professional image manipulation: it's compression scheme is good and 8uc{3,4} is lossless, but beyond 8bpc you're out of luck. I'd love to have a wide-supported float32 format with reasonable lossless (and maybe lossy) compression options. Conversely, FLAC supports different resolutions and sampling rates, so it does do the job for the sound processing.
