Bug fixes:


- Use "scale" mode as default.
This cleans up more confusion between mode and direction.
See also `plone.namedfile issue 102 <https://github.com/plone/plone.namedfile/issues/102>`_.
Previously our definition of the ``IImageScaleFactory`` interface had the deprecated ``direction="thumbnail"``.
Other parts used ``mode="contain"`` by default, which does cropping, where in Plone we are used to simple scaling almost everywhere.

--------------------

Bug fixes:


- Fix to ensure that when a scale that was registered using `pre_scale` is
later actually generated by `get_or_generate`, it is stored with the same
uid as the placeholder info that was stored by `pre_scale`. This avoids
an issue where the same scale was generated repeatedly.

--------------------

New features:


- Pre scale: store non-random uid to prepare space for a scale.
You call ``pre_scale`` to pre-register the scale with a unique id
without actually doing any scaling with Pillow.
When you later call the ``scale`` method, the scale is generated.
You can still call ``scale`` directly without first calling ``pre_scale``.
