I have looked everywhere for something nice from glib, but I'm not
seeing it.  As far as I can tell, most people just do the bit shifting
manually -- but that's what I had originally and you didn't like it.
So I'm only seeing 2 options here, this way or the original way.  If
you know of the glib function to use, please let me know what it is.
