Hmmmmmm.  Because of this include, should fake video frame go in compositor
bindings? Also, move the include to the .cc file.

There was some migration path for getting rid of WebVideoFrame entirely, which
has currently ground to a halt I guess. I think this should stay here, and
eventually WebVideoFrame becomes cc::VideoFrame, or media::VideoFrame, or
something.

+namespace cc {
+
+class FakeVideoFrame : public WebKit::WebVideoFrame {
+ public:
+  explicit FakeVideoFrame(const scoped_refptr<media::VideoFrame>& frame);
+  virtual ~FakeVideoFrame();
+
+  virtual Format format() const;

OVERRIDE? Also, maybe add a // WebVideoFrame interface comment like we do
elsewhere in cc?

Comment added. OVERRIDE across the WebKit boundary seems to be more trouble than
good. See FakeWebGraphicsContext3D for a counter-example.
