Deal in solid angle fractions, not absolute solid angles.
* src/extent-sampling.sc (volume-cone): Use solid-angle-fraction->planar-angle instead of solid-angle->planar-angle. * src/nd-random.sc (planar-angle->solid-angle): Rename to planar-angle->solid-angle-fraction and return a solid angle fraction. (solid-angle->planar-angle): Rename to solid-angle-fraction->planar-angle and accept a solid angle fraction. (hollow-cone-random-vector): Use planar-angle->solid-angle-fraction instead of planar-angle->solid-angle. (beta-inc-unnormalized, incomplete-wallis-integral): Delete functions. * include/nd-random.h (planar_angle_to_solid_angle): Rename to planar_angle_to_solid_angle_fraction. (solid_angle_to_planar_angle): Rename to solid_angle_fraction_to_planar_angle. * scm/nsmc/wrap.scm (planar-angle->solid-angle): Rename to planar-angle->solid-angle-fraction.
