commit e2b89503cd7cd3e4942877894d4b8b7f1a44ba6b
Author: Paul Ramsey <pramsey at cleverelephant.ca>
Date:   Thu Nov 5 11:46:02 2020 -0800

    Swap axes that have 'Lat' in the first axis. Don't swap axes that are 'Easting' first. After that, believe the directionality provided and swap any 'north' axes. If you still don't know what to do, just leave the axes alone.
    Closes #4748
