Subject : Mac: Loosen CoreAnimation blacklist on 10.10 and histograms to watch
Author  : ccameron
Commit description:
  
This was only ever observed on this particular GPU.

Add histograms to watch glFlush and CATransaction time, since they
(in addition to IOSurface create and texture bind) are places where we
see hangs.
