I'm against exposing the thumbnails at all. This has severe impact on KWin's 
rendering performance. The taskbar thumbnail effect is designed for the usage 
in the thumbnail were a few assumptions hold, mainly the fact that the window 
is on top of all windows. Adding a plasmoid on the desktop rendering a 
thumbnail could crawl kwin down completely.

So what's actually the use case of Thumbnails is Plasmoids? Remember a 
thumbnail has to be of at least 200x200 pixels to be of use.
