Attachment: Turns on Tiled Thebes

This patch turns on Tiled Thebes Layers for MOZ_HAVA_COMPOSITOR or gonk builds.

Using the tiled thebes layer makes the problem go away in B2G. Still need to determine root cause.

Turns on Tiled Thebes

Perfect.

We can defer investigating the bug in the other path until after gralloc support lands.  It's not clear a priori which path will be faster, and not worth investigating until gralloc.  Please file a followup bug for that and have the gralloc bug block the followup.

dhylands, whups!  You want to set the Keyword, not the Whiteboard! :)

(Yes, that's pretty confusing, sorry.)

I tried this patch on the device and saw a new assertion:

Out-of-process content won the race with this patch due to the unfortunate checkin-needed issue, so we have to wait on bug 747811 now.

Closing this bug since it isn't relevant any more.
