Enclosed is include/osgParticle/Particle. I removed the const from the
return type of getSTexCoord. I also changed the name on the next
function to getTTexCoord so it is consistent with getSTexCoord. If you
prefer to change getSTexCoord to getSCoord you will need to change it in
ConnectedParticleSystem.cpp."
the position of the emitter in the previous frame and the new position in the new
frame, the number of particles added also scales up to compensate for this movement.
Clients just have to call Particle::setTextureTile() and specify the number of
horizontal and vertical tiles that make the animation up in the texture image."

"Most relevant news:
1) particle systems now have the "freezeOnCull" property set to false by
default. Since it is an optimization, and using it may cause some unwanted
behaviors if not handled properly, it makes more sense to turn it off by
default.
2) new "LINE" shape mode which uses GL_LINES to draw line segments that
point to the direction of motion.
3) particles can now have a rotation angle and angular velocity.
4) new AngularAccelOperator applies angular acceleration to particles.
5) particle processors such as emitters and programs can have a "start",
"end" and "reset" time coordinate. For example, an emitter may be instructed
to start emitting particles only after a certain time, stop after another
amount of time and then start again.
Update (2) is from Gideon May.
Updates (3) to (5) are from Douglas A. Pouk."
