@jbridson This is exactly the kind of magic numbers dance that we try to avoid with grid variables (applies to the whole commit).
If *any* numbers other than that are necessary, please document *why*.
For example: "Needs to subtract half the button width for center placement".
Otherwise other devs have no chance of maintaining this stuff.
