[SDL] How calculate the frame per seconds

[Will McGugan]

All you are calculating there is the time per frame. You want to find how
many times you can do that per second. So fps should be 1.f / (
(float)(newtime - oldtime) / 1000.f ). Although you would be better of
taking a sample over a number of frames..
