+The Client MAY set this property to hint the compositor that the
+window would benefit from running uncomposited (i.e not redirected
+offscreen) or that the window might be hurt from being uncomposited.
+A value of 0 indicates no preference. A value of 1 hints the
+compositor to disabling compositing of this window. A value of 2 hints
+the compositor to not disabling compositing of this window. All other
+values are reserved and should be treated the same as a value of
+0. The compositing manager MAY bypass compositing for both fullscreen
+and non-fullscreen windows if bypassing is requested, but MUST NOT
+bypass if it would cause differences from the composited appearance.

+Rationale: Some applications like fullscreen games might want run
+without the overhead of being redirected offscreen (to avoid extra
+copies) and thus perform better. An application which creates
+pop-up windows might always want to run composited to avoid exposes.
