Support for grouped rendered opacity?

That should absolutely not be happening. In fact, it is explicitly the semantic of 2D opacity that we render the node into an image, and then apply the opacity to the image. So I don't know how the individual child node's opacity could be changing.

When I am changing the opacity of a panel with multiple node children, what I am seeing is the individual opacities of each child node changing, which is not what I am aiming for.

What I was hoping to achieve was to change the opacity of the *rendered* pane. Is that possible?
