Bug report

Bug summary

I can't figure out how to stop the cocoa mainloop once it's going with the macosx backend. This could be a missing API, or just one that I don't know about.

I suspect an API that exposes sending [NSApp stop] is all that's needed, but I'm not sure.

Code for reproduction

import matplotlib
matplotlib.use('macosx')
import matplotlib.pyplot as plt
from matplotlib.backends.backend_macosx import TimerMac, show

def stop_mainloop():
    print("I don't know how to quit you")
    t.stop()

t = TimerMac(2000)
t.add_callback(stop_mainloop)
t.start()

show.mainloop()

Actual outcome

Loop runs forever because I don't know how to stop it.
