Projecting the disk onto the hemisphere requires "blowing up" the set of
samples in order to prevent samples "sticking" nearby the edge of the
sphere/disk. The surface near the center of the disk grows more than the
surface near the edge, so near the center the samples move farther away.
That results in an uneven distribution.
