Stop using mixed enum arithmetic

    XMLWordPrintable

Details

    Description

      C++20 deprecated (and C++23 will likely remove) arithmetic between mixed enumerations, as well as enumeration/floating point operations.

      We're using it all over the place, causing countless warnings in GCC11 in C++20 mode. We need to port away from it.
