Begin atlasing

Begin atlasing

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.

should be make this a flags bitfield (with only one flag defined for now)?

PLA @ PS 7. It contains the new flags.

PLA -> PTAL
