I wish there were some better way to do all of these.  Maybe
s/private/protected/ below would let FakeContentLayer expose these functions,
rather than putting them on TiledLayer?

I kinda like them here because they are closer to the real code, so you can more
easily see the relationship to the real code, and maybe they have a better
chance of staying correct over time. With the ForTesting, it prevents anything
else from using it.

But, I'm okay with moving them entirely to the FakeContentLayer too.

I will also say, I like this a bit better than making m_tiler protected, because
that exposes it for non-testing code. Whereas this does not.

 
 private:
     virtual scoped_ptr<LayerImpl> createLayerImpl(LayerTreeImpl* treeImpl) OVERRIDE;
