Destructor
The Destructor modier enables you to destroy (i.e. remove) particles from the particle stream.
Particles are affected by the destructor if the origin of their local axes lands within the boundaries of
the destructor (the size of the particle object plays no part here).
So that the destructor has a denite effect, i.e. destroys particles, it must have a minimum thickness
greater than the distance covered per frame by the particles. For example, if a particle is in front of
the destructor at frame 20 and then past the destructor at frame 21, it will not be destroyed, even
though it has effectively passed though the destructor. The particle must be inside the destructor to
be destroyed at that frame.

Affects how many particles will survive.
 0% - All particles are destroyed.
 n% - n% of the particles remain.
 100% - All particles pass through the destructor.
