Would this be cleaner with FrameRateTestVariant having a bunch of bool fields
instead of an enum? You'd still need the PrintTo code, but it'd be a lot easier
to read the printTo  function...

can't you do suffix = (GetParam().GetFlags() & kReference) ? "_ref" : "";

The string being passed in here is what the performance graphs use --- name is
which graph its part of, and trace_name is the data series. (Maybe we should
s/trace_name/data_series)

     printf("GESTURES %s: %s= [%s] [%s] [%s]\n", name.c_str(),
                                                 trace_name.c_str(),
                                                 results["gestures"].c_str(),
