In /etc/ImageMagick/policy.xml
what is MiB and MB?
There is no explanation there. I guess both are mega-bytes, but why use two symbols?
Please clarify.

Ki, Mi, Gi etc are binary prefices, where 1 Ki = 1024.

K, M, G etc are decimal prefices, where 1K = 1000.

See https://en.wikipedia.org/wiki/Binary_prefix

Thanks. Didn't know that it is a standard.
