/** @brief CCParticleSystemPoint is a subclass of CCParticleSystem
Attributes of a Particle System:
* All the attributes of Particle System

Features:
* consumes small memory: uses 1 vertex (x,y) per particle, no need to assign tex coordinates
* size can't be bigger than 64
* the system can't be scaled since the particles are rendered using GL_POINT_SPRITE

Limitations:
* On 3rd gen iPhone devices and iPads, this node performs MUCH slower than CCParticleSystemQuad.
