I changed them all before, but that ends up modifying the api and making the changset larger than it has to be.  I got a little pushback on rolling that in along with a move to unsigned, so I went the other way this time and minimized it.

If we're going to change the name, I'd like to do it while also flipping most of these values for to unsigneds for extra compiler checking.  Just flipping the names alone makes it harder to accept patches for no real benefit
