Encapsulate canvas element in FrameRenderer

Browse Source 
From this change set, the HTML canvas element, which is the frame view,
is encapsulated inside the FrameRenderer.
You won't need to give the view handle from the controller layer
anymore.
It will make view alteration implementations much easier (like grid for
instance)
