Description: This is still a prototype, but it seems to work. make figures be able to keep track of if they need to be re-drawn. There is already a call back system in-place for when Artist properties change (see Artist.{add,remove}_callback and Artist.pchanged) which we can tap into to set axes/figure trees as 'dirty'. This will useful if we ever want to start caching rasters of each artist (does that even make sense? I think it does and is an obvious place to get major gains if we do not re-render the text each time) use the plugable interface in IPython make sure that calling the install function multiple times does not do funny things. make sure mplot3d is not broken calling plt.install_repl_hook() fig, ax = plt.subplots() ax.plot(range(5)) will automatically re-draw the figure as expected. If we are happy with this, running the installer should probably be part of the pyplot import. attn @efiring this is the alternative to the approach in #4082 that I was talking about in MD.
