call canvas.draw() which creates the renderer and calls
fig.draw(renderer). The segregation between the canvas and the figure
was done precisely to decouple the backend (eg renderer) from the
frontend (eg figure).
See examples/dynamic_image_gtkagg.py for an example of how to
dynamically update the gtkagg canvas.
