Instead of having two virtualizations of the canvas we push the virtualization into the canvas code itself. This not only avoids the duplication of this code, it also makes the exposed API for the canvas much smaller (in terms of exported API). It also lets us use the virtualization to implement basic support for operations in canvas_base which is then overridden by each canvas implementation.
