Implements pointer barriers as specified by version 5 of the XFIXES protocol. Barriers are axis-aligned, zero-width lines that block pointer movement for relative input devices. Barriers may block motion in either the positive or negative direction, or both. v3: - Fix off-by-one in version_requests array - Port to non-glib test harness - Fix review notes from Søren Sandmann Pedersen, add tests to match Co-authored-by: Peter Hutterer <peter.hutterer@who-t.net> Tested-by: Peter Hutterer <peter.hutterer@who-t.net> Signed-off-by: Adam Jackson <ajax@redhat.com> Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>
