XML/Projectile particle


 * 
 * A bitmap file used to map the alpha of the particles.
 *  Model used as the projectile.
 * 
 *  Offset the origin of the attack; +X is to the right of the attacker, +y is above the attacker, +z is to the front of the attacker. Make no difference to the endpoint
 * ; Starting color/transparency, ranges from 0-1
 * ; Ending Color, same range
 * size of texture when particle is created
 *  size of texture when particle has emitted all energy
 * The speed (Distance moved really) of the particle over their lifetime
 * How much particle are effected by gravity
 *  The amount of particles emitted
 *  Maximum Energy
 *  Variation
 * Trajectory types are mutually exclusive
 * Speed of the projectile - negative values and 0 have interesting, but not terribly useful effects.
 * Speed of the projectile
 *  Height of the parabolic arc
 * 
 * Width of the spiral
 *  How often the spiral, uh, spirals
 * 
 * <speed value="4.0"/>
 * Width of the spiral
 * <frequency value="0.5"/> How often the spiral, uh, spirals
