Hi Jacopo,
Thank you for the patch.

I like how the CameraDevice uses the CameraCapabilities, it makes
CameraDevice a lot cleaner. I was expecting a bit more to reduce
duplication in the functions that CameraCapabilities has, but that can
be done on top. I think this is a good start, and we can build on top of
this.
I'm not going to confirm the copy-and-paste :D

It also doesn't regress CTS.
