SDL::Timer - a SDL perl extension to handle timers
$timer = new SDL::Timer { print "tick"; 4000; } -delay => 4000;
SDL::Timer
provides an abstract interface to the SDL::Timer
callback code. SDL::Timer::new requires a subroutine and a delay
at which is the initial interval between the creation of the
timer until the first call to the subroutine. The subroutine
must return a value which is the delay until the it is called again.
