Pekka Paalanen baf7ab5795 tests/alpha-blending: use two_norm tolerance
Switch from per-channel max error tolerance to max two-norm (Euclidean
distance) error. Geometrically this means that previously the accepted
volume was a +/- tolerance cube around the reference point, and now it
is a sphere with tolerance radius. This makes the check slightly
stricter.

The real benefit is simplifying the code.
