This renames the following (in alphabetical order, non-exhaustive):
AudioCaptureStream -> AudioCaptureTrack
AudioNodeStream -> AudioNodeTrack
AudioNodeExternalInputStream -> AudioNodeExternalInputTrack
DirectMediaStreamTrackListener -> DirectMediaTrackListener
MediaStream -> MediaTrack
- Note that there's also dom::MediaTrack. Namespaces differentiate them.
MediaStreamGraph -> MediaTrackGraph
MediaStreamTrackListener -> MediaTrackListener
MSG -> MTG (in comments)
ProcessedMediaStream -> ProcessedMediaTrack
SharedDummyStream -> SharedDummyTrack
SourceMediaStream -> SourceMediaTrack
StreamTime -> TrackTime
TrackUnionStream -> ForwardedInputTrack
- Because this no longer takes a union of anything, but only a single track
as input.
Other minor classes, members and comments have been updated to reflect these
name changes.

* Implementation of https://dvcs.w3.org/hg/dap/raw-file/default/media-stream-

|
* capture/ImageCapture.html.
|
|
* The ImageCapture accepts a video MediaStreamTrack as input source. The image
|
|
* will be sent back as a JPG format via Blob event.
|
|
*
|
|
* All the functions in ImageCapture are run in main thread.
|
|
*
|
|
* There are two ways to capture image, MediaEngineSource and MediaTrackGraph.
|
|
* When the implementation of MediaEngineSource supports TakePhoto(),
|
|
* it uses the platform camera to grab image. Otherwise, it falls back
|
|
* to the MediaTrackGraph way.
