Zooming on Basemap plots loses Axis Ticks #342

Axis used in Basemap plots loses the tickmarks when plot is zoomed.

I would suggest a boolian operator to allow for readjustment of axis ticks?

Unfortunately, it isn't as easy as just a boolean flag to allow readjustment of the ticks. The way the ticks are computed right now is a bit hacky, and zoom/pan barely works as expected right now as it is. What may work is to register a callback function that does the tick draws on the axes limits changed event.

As you may or may not be aware, basemap is currently in a long-term deprecation process (all new development efforts should be directed to cartopy). I'll certainly review any pull requests for bug fixes and/or new features, but come 2020, we should all have transitioned over to cartopy.
