-//        recording and playing, you should move the relevant windows
-//        to constant sizes and locations.
-// TODO(mbelshe) For now this is a singleton.  I believe that this class
-//        could be easily modified to:
-//             support two simultaneous recorders
-//             be playing back events while already recording events.
-//        Why?  Imagine if the product had a "record a macro" feature.
-//        You might be recording globally, while recording or playing back
-//        a macro.  I don't think two playbacks make sense.
