TYPO3.Imagine

TYPO3.Media currently holds a Transform service, but Imagine doesn't

This should be ported to Imagine and give a Interface for other to work against. Copy from IRC chat

[14:38] bwaidelich: so my suggestion would be: move the concrete implementation to the imagine package (as you did) and introduce an ImageTransformerInterface (or similar)
[14:41] bwaidelich: but again: i think, your change makes absolute sense. only, if you are going to remove the service from the Media package i'd suggest to add a new interface and code against that in the Media package
[14:41] sorenmalling: bwaidelich: I like that suggetion, IMO Imagine should be shipped with some sort of service library, so you don't have to rewrite it your self, or depend on some other packages domain model (ex. TYPO3.Medias transformservice only "accepts" TYPO3.Media Image domain model)
[14:41] bwaidelich: then the only dependency to Imagine would be in Objects.yaml
