Blur whatever's behind the window

[depau]

Add an option to blur everything behind a window (like on mac os x) so that translucent windows look better. Also add the option to enable this for focused windows.

Transparency blur would really add a whole new level to theming Gnome 3. Transparency blur is the only feature I miss from previous desktops, now that I've fully migrated over to Gnome.

Hereis the link that got me hooked on it in the first place if you'd like or need an example.
If us theming-inclined folks had access to transparency blurring in any capacity, the eye candy would get so much sweeter- and this is the closest I've seen so far.

Transparency as it stands is almost useless since background content obscures foreground content. I'd love to know if this is possible within the scope of an extension. Either way, keep up the good work. 👍
