Since a4c79d695d52c94647b1aff7 the constant BILINEAR_INTERPOLATION_BITS must be strictly less than 8, so fix the comment to say this, and also add a COMPILE_TIME_ASSERT in the bilinear fetcher in pixman-fast-path.c --- pixman/pixman-fast-path.c | 2 ++ pixman/pixman-private.h | 2 +- 2 files changed, 3 insertions(+), 1 deletion(-)
