Stop Unity from redrawing the shell on every frame (ie. when it doesn't need
to). It had a severe impact on graphics performance. (LP: #988079)
This especially improves OpenGL application performance and multi-monitor
desktop performance. Because unity was previously slowing down compiz
rendering by 20-40% for each monitor added to the system. This slowdown no
longer occurs as only damaged areas of the unity shell are repainted. Now
unity will not have any impact on compiz rendering performance for most
video frames.
Coincidentally, this fixes a number of other bugs (linked)..
