Currently tiling+shmem means no gralloc, means no hardware composer, means too much power. As we consider bug 915673, turn back to buffer rotation+gralloc to let JB HWC work continue.

To not mess up the power consumption numbers and JB HWC work, turn the tiling back off for now.

in layout/reftests/forms/input/range/reftest.list you'll need to mark the step-down tests (lines 22 and 23) as fails-if B2G

What bug regressed this that should be noted in "Blocks:" -- was it the layer refactoring metabug?

It's QC reported power consumption issue because hardware composer isn't being used. There was no functional regression that we know of.

After disabling tiling on b2g, we should not enable it until we confirmed that the tiling do not regress the important use cases(home screen, video playback, mail edit). Low power consumption is one of the most important competitive features.
