GSimpleParticle class
A particle used in a GSimpleParticleSystem. This class is used internally by the GSimpleParticleSystem class and is not intended for direct usage.
The rendering uses LinkedLists, so the particle is a node in a list.
Constructors
- GSimpleParticle()
- Creates a new GSimpleParticle instance.
