Plone.scale

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

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``.

Bug fixes:


- Minor cleanup: isort, black. [maurits] (59)

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

Bug fixes:


- Fix cropping when the height is not limited.
Create a square then.
Not limited means: 65000 or larger, or zero or lower.

- Fix cleanup of scales: only throw away outdated scales of the same field.

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

Bug fixes:


- Fixed ``DeprecationWarning`` with Pillow 9.1.0 for ``ANTIALIAS``.
Use ``Resampling.LANCZOS``, falling back to ``ANTIALIAS`` on older Pillows.

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

Breaking changes:


- Removed deprecated ``factory`` argument from ``scale`` method.
This is in the ``AnnotationStorage`` class and the ``IImageScaleStorage`` interface.
This was already scheduled for removal in ``plone.scale`` 3.0, but was kept longer.
Fixes `issue 47 <https://github.com/plone/plone.scale/issues/47>`_.

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

Breaking changes:


- Removed docs directory and sphinx extra.
The docs were last updated in 2010, and the maybe still relevant parts already copied to the readme.

- Removed ``tests`` extra, kept only ``test`` extra and ``storage``.
Swapped packages slightly between those two extras.
For ``storage`` we depend on ``persistent`` and ``ZODB``.

- Depend on Pillow.
Originally we did not officially depend on it (or PIL) "because not everyone can install it as an egg".
It seems time to grow up here.

- Removed Python 2 support. Only Python 3.6+ supported now.
Still works on Plone 5.2.
