Bug Description
Since windows that are composited consist of textures that are tracked by the compositor it should be possible to get those window textures and their extents out of the compositor.
This will enable nice looking screenshots with alpha transparency, rounded corners and native shadows.
In a rectangle selection scenario the windows enclosed by the rectangle should be recomposited to remove the desktop background and map it to zero opacity.
• Compiz has a screenshot plugin. It might be extended to do this.
• KWin compositor has a screenshot plugin that does this already
• Both recent Windows and OSX do this already.

I am aware of the problem, but I don't have the time to work on this currently. I have also filed a bug for this some time ago: /bugs.launchpad .net/unity/ +bug/781280

Any help would be very much appreciated.
