Er, what alignment?
Either the CPU or something else assumes and requires alignment, in which
case we know that we can happily abuse the low-bit of the address.
Or it doesn't, in which case we can add our single byte and use it with
impunity. And yes, Allen's right that if we're going to add a single byte
to the structure we should just put the colour information into that
instead of using it to align the pointer so that we can abuse the low bit
of the pointer :)
