Subject: Fix composite on big-endian systems.
X-Git-Tag: pixman-0.17.2~50
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f135f74ff3a4f55262b611b452566daff5e936ce;p=platform%2Fupstream%2Fpixman.git

Fix composite on big-endian systems.

Data narrower than 32bpp is padded to an unsigned long and on
big-endian systems this shifts the value by the padding bits.
