This is marked as a FAIL_TEST, because the last image comparison fails due to a bug in Weston. Jointly authored by Pekka and Emilio. Signed-off-by: Pekka Paalanen <pekka.paalanen@collabora.co.uk> Signed-off-by: Emilio Pozuelo Monfort <emilio.pozuelo@collabora.co.uk> Reviewed-by: Micah Fedke <micah.fedke@collabora.co.uk> [Pekka: move weston-tests-env as terminator to EXTRA_DIST, change ok/FAIL to PASS/FAIL, write diff image only on fail.] Acked-by: Quentin Glidic <sardemff7+git@sardemff7.net>dev
