I don't think this should be a todo. What needs to be done to implement this
properly?

[sohanjg, 2014/07/28 10:10:19]

For getting correct tree we need to set which tree during tests explicitly,
which will involve changing and verifying all tests using
FakePictureLayerTilingClient i.e PictureLayerTiling and PictureLayerTilingSet
tests.
So i thought of doing it as a seperate CL, right after this gets landed.
