Image.draft() return value
^^^^^^^^^^^^^^^^^^^^^^^^^^
The ``Image.draft()`` method used to return ``None`` or the image itself.
Unlike other `chain methods`_, ``draft()`` modifies the image in-place
rather than returning a modified version.
In the new version, ``draft()`` returns ``None`` if it has no effect or
a tuple of new image mode and the box of original coordinates in the
bounds of resulting image otherwise
(the box could be useful in subsequent ``resize()`` call).
