  ### Unreleased
  +Bug fixes:
  +- Calling `DynamicImage`/`ImageBuffer`'s methods `write_to` and `save` will now
  + work properly even if the backing container is larger than the image layout
  + requires. Only the relevant slice of pixel data is passed to the encoder.
  +
  - More convenient to use differently laid-out buffers for initialization and
  results, but not operation directly, will be added in the future. The plan
  is for these to use a byte-based interface similar to `ImageDecoder`.
