It's all bit twiddling with curses properties, you just don't
see the bits because everything has predefined constants.
But if you were perverse you could just pass binary
integers instead. If you print the constants you'll
see the integer values.

But I can't think of anything useful you could do by
manipulating the masks with shifting or xor-ing them.
Maybe flipping between two attribute styles would work,
but it's just as easy to apply two defined bitmasks.
