Detailed Description

An EmitterVolume that emits particles from the interior of a cone.

The points are distributed uniformly in the volume using this function:

    Given the values r and h, and the random values t:[0,1), u:[0,1), and
    v:[0,1),
    
        x = sqrt( t ) / r * v**(1/3) * h * cos( u * TWO_PI )
        y = sqrt( t ) / r * v**(1/3) * h * sin( u * TWO_PI )
        z = v**(1/3) * h
