Id -> ID

[wjia(left Chromium), 2011/06/01 03:30:52]

Done.

+typedef std::pair<int32, int> VideoCaptureControllerID;

[scherkus (not reviewing), 2011/05/31 20:42:00]

did you see darin's comment about using a struct instead of std::pair?

+// VideoCaptureControllerEventHandler is the interface for
+// VideoCaptureController to use VideoCaptureHost services.

pedantic nit: VideoCaptureController doesn't know that VideoCaptureHost exists
hence this interface

Otherwise you'd be passing in VideoCaptureHost pointer directly and do away w/
this class :)
