Registered by Sergey "Shnatsel" Davidoff

When there's a window open, blur the desktop background so it doesn't get in the way.

Status:
 * Blur support is already there, but there's currently no way to detect if there are any windows on the screeen/workspace. Might be done with some focus tricks maybe, or just by walking libwnck's window list.

Things to think about:

 * Blur handling:
     - we use crossfading to the pre-rendered blurred image for transition - when to blur it and how store it?
     - we need the blur radius to be adaptive to screen size - what's the exact formula?
     - when using several monitors, blur the pic only once for the largest screen and scale it to fit the others

While this is a nice concept, there are other things we need to focus on right now. Deferring to L+1. ~cassidyjames

Okay, I have a proof-of-concept implementation in lp:tilt-shift-desktop/bash
