Compiz's Modal Dialog plugin features new effect

Few days ago we saw the "real" implementation of Compiz's modal dialog plugin (both the actual plugin and the theming) but the "effect" that was standing between the active window and the child dialog was blurred white-ish.

In Oneiric, the Modal Dialog plugin has received just now a black-ish unfocused background (the main window) that fits perfectly in the scheme, it is quite easy to observe the white dialog standing on the black unresponsive-like window.
