These alternate-rendering-mode ("-pipe cross-process", "-serialize", etc.)
rebaselines will not work.

GM assumes that alternate-rendering-mode results MUST EXACTLY MATCH the results
of standard rendering.

Hence, in
http://108.170.220.120:10117/builders/Test-Ubuntu12-ShuttleA-GTX660-x86-Relea...
, not only did the CompareGMs step fail ("some images did not match the
expectations checksums"), but the GenerateGMs step failed too:

P.S. This is the platform affected by http://skbug.com/2575 ('GenerateGMs is
flaky on Test-Ubuntu12-ShuttleA-GTX660-x86-Release'), which is I guess why we
saw these failures.
