Do you still need these override?

[sadrul, 2015/03/26 04:36:39]

We still need to override these for CompositorWorkerThread, yes. But the current
implementation in this CL don't do anything. So I have removed these. In
subsequent CLs, these functions will be overridden with proper implementation.

ok, it makes sense.  lgtm
