### Changed

When requesting a lossless image from the [VIP File System](https://docs.wpvip.com/vip-file-system/)
and specifying a quality value lower than 100, the image is now returned compressed
in a lossy manner, instead of ignoring the quality request.

### Added

The `allow_lossy=1` query parameter has been added to opt-in to lossy compression
for lossless images without having to specify a quality value. The VIP File System
will tune compression based on the image and context.
