If this flag is set, the time_step
variable is locked to fps_max, regardless of the real
frame duration. All functions using time_step - i.e. all speeds - will
then become frame rate dependent.
on - time_step depends
only on fps_max
off - time_step depends
on the real frame rate.
fps_max = 60;
#ifdef TEST // use this for test purposes only!
fps_lock = on; // time_step is now always 16/60 = 0.266 ticks
