MNT : remove stale flags from Axes.draw

tacaswell · tacaswell · commit 9706cc093356 · 2015-05-25T00:50:37.000-04:00
The first pass at getting this to work put all of the logic to label
artists as not stale in the Axes.draw method.  Now that all of the draw
methods are marked up this is not needed.
