Comment 36 for bug 87947

Thanks for testing! The handoff patches are based on libxcb git commit 7a74ba3d0212f9bfe021d6da9070f71cbc53f85b and libX11 git commit 64325f38bab082a8e0e9ce779a8e582de5c8588e. It'll probably apply against newer versions of libX11, but there's been a lot of work in libxcb since we started trying to make this new handoff approach go, so I'm not surprised the patches don't apply.
