- Add a bunch of types & methods that aren't used yet. The idea is
creating the output from the known input parameters is pure, and works
for any uploaded media
- Introduce a new kind of media "animation" which is neither an image
nor a video. It is likely that animations can be processed properly at
the /image/process.{ext} endpoint with a little massaging
TODO:
- Integrate this into exiftool, ffmpeg, magick commands
- Detect apng with ffmpeg (imagemagick treats it as a still png unless it's given a
hint)
- Infallible conversion from Details to OutputFile - this might be
impossible given that we don't currently store more than a mime type
and a frame count to give any sort of indication of real type
- Try not to break API
