Animate calls a function repeatedly like setInterval() but with the current time (Date.getTime()) and the difference to the last call in milliseconds as parameter
when using _AddOptions( "NoDom" ); to cause a high performance you cannot use SetInterval but Animate.
comparison:
normal:
setInterval: about 242 calls per second
app.animate: about 217 calls per second
with "NoDom" option:
setInterval: error
app.Animate: max. 600-750 calls per second
