I'm a little confused why this is necessary.

It's my expectation that initially and on resize there's an invalidation for the entire layer size.  If that's the case, then the only time you would have partial tiles filled up would be on the edges.  Because you have to repaint on resize anyway, this shouldn't be a problem.  Is this not true?

If this really is a problem, then I think the right fix here is to just change the tiler to have an explicit setLayerSize() function, rather than attempting to implicitly calculate it and grow to be the right size.

It's my fault it's that way in the first place, but I think growLayerToContain is a backwards way of handling the layer size.  It'd be nice to not go even further down that path.
