/*

|
EXPLANATION:
|
|||
|
|
|||
|
ParticlesManager improves the old particles system as follows - the particles manager stores the
|
|||
|
last particles configuration which had some particle rendered by a thread.
|
|||
|
Under normal cicumstances, this means that every thread has the particles configuration that rendered
|
|||
|
last. In case a trail was set, such frame is that beyond the trail.
|
|||
|
This managemer works well on the assumption that each thread builds particle in an incremental timeline.
