[PATCH weston 6/7] tests: add subsurface-shot test
Emilio Pozuelo Monfort
pochu27 at gmail.com
Fri Jan 27 16:30:28 UTC 2017
From: Pekka Paalanen <pekka.paalanen at collabora.co.uk>
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.
