What I had in mind:

1. Adding the ability to change the label’s JustifyH
2. Adding the ability to change the label’s JustifyV
3. Letting the programmer decide where the label’s image is anchored

The first two changes are quite trivial:

local methods = {
    ...
    ["SetJustifyH"] = function(self, justification)
        self.label:SetJustifyH(justification)
    end,
    ["SetJustifyV"] = function(self, justification)
        self.label:SetJustifyV(justification)
    end
}

I'm especially interested in the justification personally.
