There's an issue with adding some of the tilings, since the scales
collide (or are not valid otherwise), which is causing some DCHECKs
to be triggered.

This just shuffles the scales, as well as make the layer smaller so
that we don't create massive amounts of textures (which is pretty slow
even on my desktop).
