Fix for bug #13363: ray (qmc) shadows had some light leaking issues,
due to jittering of the start position for antialiasing in a pixel.

Now it distributes the start position over the fixed osa sample
positions, instead of of random positions in space. The ugly bit is
that a custom ordering was defined for osa 8/11/16 to ensure that the
first 4 are distributed relatively fair for adaptive sampling to decide
if more samples need to be taken.
