Why don't use `Date.now()` ?

[finscn]

I found there are some `new Date().getTime()`  in Babylon's source , 

Why don't use `Date.now()` ?

IE <= 9 support.

Why dont we just add this polyfil?
 

if (!Date.now) {
  Date.now = function now() {
    return new Date().getTime();
  };
}

BJS doesn't support IE <= 9.

IE doesn't support WebGL until version 11.

well that would be the only reason to not use Date.Now() as it has more performance.  So I second fin's question then, why do we not use it?

[JCPalmer]

Reference should all be to BABYLON.Now. window.performance.now, if available uses more precision than getTime().

perfomance.now will never be a bottleneck in BJS, but for educational purposes:

I think we should use `Date.now()`  instead of  `new Date().getTime()`

Will update all references to date.now in next commit
