View source for WebAPI/CameraControl

This is a proposal for an API to control a camera which goes further than the [https://bugzilla.mozilla.org/show_bug.cgi?id=692955 Camera API] and [https://bugzilla.mozilla.org/show_bug.cgi?id=665909 WebRTC] and may be required in order to build a camera web app equivalent to native camera apps in terms of functionality and user experience.

It is not clear which of these use cases should be satisfied by an API, by the implementation of that API or an application consuming the API.
