// $Log: AvHParticleSystem.h,v $
// Revision 1.11 2002/10/16 01:03:04 Flayra
// - Added new particle flag for particles to lie flat on ground ("faceup"), needed for scanner sweep
//
// Revision 1.10 2002/07/10 14:43:40 Flayra
// - Visibility fixes (too many PSs drawing, now they expire when not visible for awhile), removed cl_particleinfo drawing
//
