If oldtime and newtime are "pretty close", you have a high frame 
rate. :-)

The delta is between the last two "loops", and where you read the 
current time and do the calculations doesn't matter as long as the 
engine does one complete loop (executing the old=new and 
SDL_GetTicks() statements) per frame at all times.
