  Capture/Replay: Add feature for robust resource init
  
  Query the feature when creating the display and the context, and
  pass the flag to the created context and also to durfaces.
  
  With that we create surfaces that will be marked "MayNeedInit" and
  are initialized if the resource is cleared or invalidated.
