 By default, result images are only saved for tests that fail.
 Enabling this option will force result images to be saved for all tests, even for tests that pass.
 
 When this option is enabled, and some hash comparison tests are performed, a hash library containing all the result hashes will also be saved to the root of the results directory.
 The filename will be extracted from ``--mpl-generate-hash-library``, ``--mpl-hash-library``, or ``hash_library=`` in that order.
