Can you provide more context about what is a |source_id| and how to get one to
make this call?

[mcasas, 2016/06/01 23:31:02]

|source_id| is the render-side identifier (UUID) of
the video capture device (webcam).
(Note that there was already a security review with
dcheng@ - also in the review list).

         => (PhotoCapabilities capabilities);
 
     TakePhoto(string source_id)
         => (string mime_type, array<uint8> data);

[xhwang, 2016/06/01 23:22:03]

What is the returned |data|?

[mcasas, 2016/06/01 23:31:02]

|data| is the Photo encoded in the format
specified in |mime_type|.
