does this have to be a member function? please move it to anonymous namespace in
.cc file if possible.

Looks like, managed_state and raster_task_ used in this func are pvt members and
cant be accessed from anonymous namespace.

[reveman, 2014/07/14 21:55:00]

Ok, just make it static and private then unless there's a good reason it's
non-static and protected.

Done.
