to bring this code more closely int how the WebKit code works, I would think
that PTEFG should return an array of event instances that get dispatched here
after executing it.

Then, do we need to change PTEFG signature in GM too..???

Currently added a separate method ForwardGestureEvents() in RootView, so that
when GM inherits from GR this function wont change at all.

     status = ui::TOUCH_STATUS_SYNTH_MOUSE;
   return status;
 }

I am reasonably strongly convinced that this is wrong: there is a
RootView::OnTouchEvent entry point above. It needs to be modified.

My Bad..Now Removed this function as no longer required with addition of
ForwardGestureEvents()
