mention coordinate space of the layer? same q about "layer" in the nam

[wkorman, 2015/11/16 19:01:03]

Renamed to layer_size.

How about storing the size, and convert to a rect when you use it? that would
keep these smaller. same q on all the others

[wkorman, 2015/11/16 19:01:03]

Discussed in person, let's try it this way, can try the other way subsequently.

   bool saved_;
 
   DISALLOW_COPY_AND_ASSIGN(CompositingRecorder);
