Remove auto-call to canvas.draw_idle in ResizeEvent processing.
Backends can call draw_idle themselves. Note that 1) this was alreadydone by the gtk backends, and 2) this may actually be unneeded, asfigure.set_size_inches (which is always called a bit earlier by thevarious resize handlers) also marks the figure as stale, which shouldtrigger a redraw too. Still, let's add the draw_idle calls to be safe,they shouldn't be costly as both draws should get compressed together;we can always investigate removing them later.
