Double pass rendering avoids overdraw problems between particle systems
and other opaque objects. If you can render all the particle systems < U > after< / U >
the opaque objects, then double pass is not necessary and can be turned off (best choice).
If you set the default attributes with < CODE > setDefaultAttributes< / CODE > , then the particle
system will fall into a transparent bin.
