The default Akamai image converter compression ratio is a bit aggressive for some images. We would like to decorate each rendition URL with a compression override lower the compression by default so that image quality is pristine by default.

There are some problems with the naive approach of saving this value directly into the content document. The first is that customers may not like the new setting, and might prefer more aggressive compression. So we would like to make it configurable.

However storing the configured value in the content document means that you cannot change the compression ratio for all content in one setting. You can only affect new content, and once created, you would have to manually update other content documents.

Proposed solution:

1. Tenant configuration of default compression ratio.
2. Publishing adds compression override to the image URL.. therefore republish picks up new defaults
3. Override setting on image rendition (needs UX design)
4. If override present, publishing ignores that rendition
