Detailed Description
A structure represent the set of properties for a basic emitter.
The structure is stored as a single optional data in the emitter
property table.
The basic emitter uses a 'time' variable to control particle
emissions. A large time gap between emission can give pulse effects
where as a small time gap produces a streaming effects. Particles
can be emitted from a single point, line, area or a volume.
Particles emitted from an emitter are of the same type. An
emitter cannot emit different types of particles. Once an emitter
has reached its maximum number of particles, no further particles
are emitted until some of the existing particles have died.
Most properties have a bias value to vary the property's value.
This uses the seed field to give a degreee of randomness.
