552 // pcolor1,pcolor2 - minimum and maximum ranges of color, randomly interpolated to decide particle color
553 // ptex - any of the tex_ values such as tex_smoke[rand()&7] or tex_particle
554 // psize - size of particle (or thickness for PARTICLE_SPARK and PARTICLE_*BEAM)
555 // palpha - opacity of particle as 0-255 (can be more than 255)

557 // ptime - how long the particle can live (note it is also removed if alpha drops to nothing)

559 // pbounce - how much bounce the particle has when it hits a surface (0-1), -1 makes a blood splat when it hits a surface, 0 does not even check for collisions
560 // px,py,pz - starting origin of particle
561 // pvx,pvy,pvz - starting velocity of particle
562 // pfriction - how much the particle slows down per second (0-1 typically, can slowdown faster than 1)
