If the pattern's dimensions are not an integer multiple of the format's block size, then do not attempt to create the discard pattern, just exit early.
I initially looked into having the pattern's dimenions adjust to the incoming block size, but it's a constant used across all APIs and multiple parts of the app, so I'm not convinced it's worth the effort. Correct me if that's wrong!
