cc.ParticleSystem setDisplayFrame 的一个错误

Cocos2d-x JavaScript
#1

setDisplayFrame: function (spriteFrame) {
if (!spriteFrame)
return;

    var locOffset = spriteFrame.getOffsetInPixels();
    if (locOffset.x !== 0 || locOffset.y !== 0)
        cc.log("cc.ParticleSystem.setDisplayFrame(): QuadParticle only supports SpriteFrames with no offsets");

    // update texture before updating texture rect
    var texture = spriteFrame.getTexture(), locTexture = this._texture;
    if (locTexture !== texture)
        //this.setTexture(texture);原来的代码
        this.setTextureWithRect(texture, spriteFrame.getRect());

},
另外，希望引擎在这里能支持旋转。
