The opacity of other piles is not changed while temp depile in some examples

In the matrix example, the opacity of other piles is not updated at all when a pile is temp depiling

In the ridge plot example, the opacity of the piles which have more than 1 items is not correct

The correct behavior should be like this

The issue with the matrices is caused by the custom WebGL program that renders the matrices. This would be solved if we implement #204 (comment)

The opacity issue with the scatterplots has never worked, unfortunately, but I found the issue 🎉As it turns out, the brightness filter causes the issue somehow. I have to find a way to properly multiply in the world alpha value. You can temporarily fix the issue by disabling pileItemBrightness
