rest - Waits a specified number of milliseconds or yields CPU. Allegro game programming library.

       This function waits for the specified number of milliseconds.

       Passing  0  as  parameter  will not wait, but just yield. This can be useful in order to "play nice" with
       other processes. Other values will cause CPU time to be dropped on most platforms. This will look  better
       to users, and also does things like saving battery power and making fans less noisy.

       Note  that  calling  this  inside your active game loop is a bad idea, as you never know when the OS will
       give you the CPU back, so you could end up missing the vertical retrace and skipping frames. On the other
       hand, on multitasking operating systems it is good form to give up the CPU for a while if you will not be
       using it.
