Fix clipping of axis artist Ticks.

QuLogic · QuLogic · commit d8ada7a2bcf9 · 2018-02-05T20:11:29.000-05:00
Instead of clipping the entire path+marker to the gc's clip path (which
is inside the Axes only), clip the *position* of the path (aka marker).
They then stay within the Axes, but don't get clipped if outgoing.
