Summary: boost::uniform_on_sphere in not uniform on sphere

Initial Comment:
It's clear that your previous (1.29) and current verisons 
(1.32) has no really uniform point distribution on sphere. 

This fact can be proved by observation that 
distributions of all coordinates are independent on each 
other.

For example for 3D-sphere really uniform distribution is 
given by Euler angles (x, arcsin(2t - 1)), where x is 
uniformly distributed random value on [0..2*pi].
