关于Hilo.drag的问题

[xiangfengsu]

写了一个探照灯效果，可是有些问题，望指教！
在快速移动dragView 的时候，graphics无法严丝合缝

测试demo

var stageWidth = innerWidth;
var stageHeight = innerHeight;
var stage = new Hilo.Stage({
container:document.body,
width:stageWidth,
height:stageHeight,
renderType:'canvas'
});
stage.enableDOMEvent([Hilo.event.POINTER_START, Hilo.event.POINTER_MOVE, Hilo.event.POINTER_END]);
var ticker = new Hilo.Ticker(60);
ticker.addTick(stage);
ticker.start();
var img = 'http://bxu2713410132.my3w.com/bg.jpg';
var bg = new Hilo.Bitmap({
x: 0,
y: 0,
image: img,
width: stageWidth,
height: stageHeight,
});
var maskBg = new Hilo.View({
x: 0,
y: 0,
width: stageWidth,
height: stageHeight,
background: '#000',
alpha: .75,
});
var graphics = new Hilo.Graphics({
x: 10+25,
y: 10+25,
});
graphics.beginFill("#000").drawCircle(0, 0, 100 >> 1).endFill();
var bg1 = new Hilo.Bitmap({
x: 0,
y: 0,
width: stageWidth,
height: stageHeight,
image: img,
mask: graphics
});
var dragView = new Hilo.Bitmap({
x:10,
y:10,
width:150,
height:150,
image:'http://bxu2713410132.my3w.com/drag.png'
});
Hilo.util.copy(dragView, Hilo.drag);
dragView.startDrag([0, 0, stageWidth, stageHeight]);
dragView.on("dragStart", function(e) {

graphics.x = e.target.x + 25;
graphics.y = e.target.y + 25;

});
dragView.on("dragMove", function(e) {
graphics.x = e.target.x + 25;
graphics.y = e.target.y + 25;
});
dragView.on("dragEnd", function(e) {
graphics.x = e.target.x + 25;
graphics.y = e.target.y + 25;
});
setTimeout(function(){
dragView.stopDrag();
},5000);
stage.addChild(bg,maskBg,bg1,dragView);

这个是因为先发了dragMove事件后再改变位置导致的，已修复。
