Composite Bypass Support Sharply Bumps XMir's Performance

Composition bypass support finally landed this morning into the mainline Mir code-base ahead of the Ubuntu 13.10 feature-freeze. With the feature being merged and packages already being pushed into the 13.10 archive, benchmarks at Phoronix have already been conducted. The benchmarks to share this afternoon are of the Mir/XMir packages from yesterday against the Mir packages today with composite bypass support. Lastly, there are benchmarks of a pure X.Org Server running on the same hardware to look at the performance impact and current (reduced) overhead of Mir.
