DelegatingRenderer: send frame on SwapBuffers instead of DrawFrame
CompositeAndReadback, though not implemented, should stay consistent. If we send
the frame on DrawFrame, we will get an Ack from the browser, even though the
frame rate controller doesn't expect one in that case. If that happens,
num_frames_pending_ becomes negative and the frame rate throttling doesn't work
any more, causing bad frames.
Instead, be consistent with GLRenderer and send the frame on SwapBuffers.
