Detailed Description

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

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

    Given the value [a,b] and the random values t:[0,1) and u:[0,1),
    
        x = a * t - a/2
        y = b * u - b/2
        z = 0
