[Bellegarde Cedric]

I now use blur plugin thanx to window matching feature, thanx David ;)

I have some bugs:

Here, i have some artefacts bugs with 4xbilinear. This blur mode is fast! May 
be a Nvidia drivers bug...

Here, an amarok big window with just desktop, moving window is fast.

Here same amarok window with a fullscreen window under it (basket already have 
blur enabled), moving amarok is slow.

Don't know really why it's slow... Maybe amarok window blur basket window that 
already blur desktop window. This may explain the slowdown... I'm really not 
sure :(
