This CL makes it possible for pulled-forward-layers to be atlased. It currently has a couple glaring limitations (which is why it is disabled): 1) the atlased layers cannot be purged nor aged out 2) the texture backing the atlas is not pulled from (or returned to) the resource cache #1 is on hold until we have a recycling rectanizer A separate major limitation (the non-atlased layers aren't cached) is blocked until we can transmute entries in the resource cache from scratch to non-scratch while potentially preserving their contents.
