Behavior changes
----------------

Locator.nonsingular return order
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

`Locator.nonsingular` (introduced in mpl 3.1) now returns a range ``v0, v1``
with ``v0 <= v1``.  This behavior is consistent with the implementation of
``nonsingular`` by the `LogLocator` and `LogitLocator` subclasses.
