patch

LCMS seems to compare all color components but gs leaves unused components
uninitialised. This causes several Valgrid warning in this case.

valgrind --track-origins=yes gs -sDEVICE=pbmraw -r72 -o /dev/null fts_25_2523.pdf

fts_25_2523.pdf is the most commonly produces rendering differences in
the regression testing. With the attached patch the run ends without warnings
(except unrelated and harmless ones). I don't know yet whether the patch fixes
the indeterminism for the lack of statistics.
