Software generally wants it in mask form.  One can do this by defining
the constants as masks or by defining the constants as bit numbers and
using "<<".  Which makes sense depends on whether anything actually
needs the bit numbers: "<<" is easy, log2() is harder, but if nothing
needs the bit numbers, just using the mask is that much simpler.
