gravity
 if set the particles will fall.

Keys:
"velocity"
 particle velocity. (default is '0 0 0)
"cnt"
 sets color of particles (default 12 - white), the colors are actually a range of 4 colors, starting with this color.
"count"
 adjusts particle density, this many particles appear every second, experiment to see the effects (default is based on area size).
"cnt2"
 random velocity adjustment, default is 0, higher makes the particles more random, 0 makes them follow velocity exactly.
