Possible solution for GSAP/tweenlite and pixi integration

pixi-tween-ticker-hack.js

PIXI.Ticker.prototype._requestIfNeeded = function() 
{
    if (!this.gsapTick) {
		//do a research, where is the passed time
		
		this.lastTime = performance.now();
	    this.gsapTick = (event) =>  { this.update(MILLISECONDS_PASSED_IN_EVENT_I_DONT_KNOW) };
		//do a research how to call it after all the other listeners
		TweenLite.ticker.addEventListener("tick", this.gsapTick);
	}
}

PIXI.Ticker.prototype._cancelIfNeeded = function() 
_cancelIfNeeded()
{
	if (this.gsapTick)
	{
		TweenLite.ticker.removeEventListener("tick", this.gsapTick);
	}
}
