3444	Allow speed of 0 in animate to be instant	jonahfox	flesler	"It would be really useful if $.fn.animate understood speed of 0 as
being instant (rather than null => default speed)

I currently use the following to achieve this :

$.fn.animate2 = function(css, speed, fn) {
    if(speed === 0) {
      this.css(css)
      fn()
    } else {
      this.animate(css, speed, fn)
    }
  } 

It is also in the best interest of accessibility to enable a way to
disable all animations across the board, so putting this somewhere in core animation functions to recognize a 0 speed animation as synonym for .css would help in those efforts, should they exist.
