TilingSprite won't display when using filters

If you assign a filter to a TilingSprite, it won't display the TilingSprite at all.
Here's a little demo showing the issue:
I could reproduce it with every filters.
```javascript
var stage, renderer, container;
stage = new PIXI.Stage(0xEEEEEE);
renderer = new PIXI.WebGLRenderer(800, 600);
document.body.appendChild(renderer.view);

var tile = new PIXI.TilingSprite(PIXI.Texture.fromImage('tile.png'), 800, 600);
stage.addChild(tile);

var colorFilter = new PIXI.ColorMatrixFilter();
colorFilter.matrix = [1,1,0,0,0,1,0,0,0,0,1,0,0,0,0,1];
tile.filters = [colorFilter]; // if you comment out that line, the TilingSprite WILL display

requestAnimFrame(animate);

function animate() {
	renderer.render(stage);
    requestAnimFrame(animate);
}
```
