If there is no problem when we don't call below two functions, LGTM.

  m_tiles.clear();
  coverWithTilesIfNeeded();

We don't need to clear tiles because TiledBackingStore didn't make them.

To be honest, I don't know what is benefit when we drop setContentsScale().

It would be nice if we set default value.

TiledBackingStore(TiledBackingStoreClient*, float contentsScale = 1.f)

Hmm, are there any reason?
We alwasys create TiledBackingStore with two arguments.

Because we have initialized the contentsScale with 1.f. 

, m_contentsScale(1.f)

I think it would be good if we keep it in constructor as well. If so, we can use a argument when we don't need to set other scale value.
