Justin’s proposed API seems to need four lines for that case:

  var t = new Timer();
  t.repeatCount = 1;
  t.addEventListener('timercomplete', function() { … }, false);
  t.start();

compared with the three for SVG’s timer:

  var t = createTimer(0, -1);
  t.addEventListener('SVGTimer', function() { … }, false);
  t.start();

Or do you mean compared to a simple function-like API, such as
setTimeout(), where it can be done in one line?  (Perhaps functions like
setHighResolution{Interval,Timeout}() would be easiest then.)
