Bug summary

FigureCanvasCairo.draw does not actually trigger a draw; it simply inherits the no-op FigureCanvasBase.draw.

See https://gitter.im/matplotlib/matplotlib?at=63305fe1aa0917742928071c for why this can be an issue.

Code for reproduction

# in an ipython shell:
matplotlib.backends.backend_cairo.FigureCanvasCairo.draw??

Actual outcome

a noop draw

Expected outcome

Probably _get_printed_image_surface can be moved into draw? Likely qtcairo/tkcairo/wxcairo could reuse some of that code too for deduplication.
