+Subject: [PATCH 13/15] Implement triple buffering for wayland
+
+Change from double to triple buffering for wayland.
+This enables higher frame rates without tearing artifacts
+by allowing both the glFinish and the buffer release
+interlock to operate without pushing the frame period
+to two vertical intervals
