Always pass size to component

[bradennapier]

Hey!
Love the this - great tool thanks as always -- pretty sure I use more of your packages than anyones. :)

Anyway, so the issue I have is that if you return height/width with the query then you will always update - losing the benefit of this component completely. However, when it does render I still need the measured height/width to operate styles etc based upon it. I think in that sense we should always get the height/width props sent down -- or perhaps at least allow us to request this action via a configuration prop?
