WebCompositorInputHandler::handle* -> InputHandlerClientImpl::Handle*?

few more comments referring to WebCompositor* in here too

Can all these function names change to chromium style?

+
+    // Called when the WebCompositorInputHandler did not handle the input event.
+    // If sendToWidget is true, the input event should be forwarded to the
+    // WebWidget associated with this compositor for further processing.

argument is webkit style (in the comment too)

+
+    // Transfers an active wheel fling animation initiated by a previously
+    // handled input event out to the client.
+    // FIXME: Make pure virtual once implementation lands on Chromium side.

TODO (or possibly this is done now?)

webkit style (in the comment too)
