support for ticks crossing axes in axisartist #19101
Description
Problem
axisartist by default draws ticks on the opposite side of the labels. It provides a method Ticks.set_tick_out() to change it to draw ticks on the same side of the label. However, there is no way to draw ticks across both sides.
Proposed Solution
Please add a function to axisartist.Ticks that enables one to draw ticks on both sides of the axis.
Additional context and prior art
Drawing tick marks spanning an axis is a common artistic choice and should be possible in axisartist.

@jasondet is there a reason you are using axisartist for your end-use rather than axis objects from the main library? Things in mpl-toolkit tend to be substantially less polished.

I actually had this mostly already implemented, see #19102. @jasondet if you are interested in the feature, consider trying to push my patch over the finish line :)

I was trying to make axes that cross in the middle of the plot rather than at the corner, like in this example. The example uses axisartist, so I tried using axisartist. I did end up doing it myself with Axis objects from the main library as axisartist was unusable.

Yes it is unfortunate that demo comes up so high in the google search. It should really have disclaimer at the top and point to the core library version: https://matplotlib.org/gallery/ticks_and_spines/spine_placement_demo.html
