// $Log: AvHSharedUtil.h,v $
// Revision 1.24  2002/11/12 22:39:26  Flayra
// - Logging changes for Psychostats compatibility
//
// Revision 1.23  2002/10/16 01:07:26  Flayra
// - Added official sizes that HL supports (ugh)
// - Added utility function for drawing range of ghost building, but it's unused
//
// Revision 1.22  2002/09/25 20:51:05  Flayra
// - Allow small items to be built on entities (health can be dropped right on players)
//
// Revision 1.21  2002/08/16 02:47:06  Flayra
// - Fixed bug where not all the entities were iterated through
// - Support for ring-drawing (but not for all entities)
//
// Revision 1.20  2002/08/09 00:51:11  Flayra
// - Cleaned up useless special casing of tracetangible, fixed some problems where buildings could be built on players
//
// Revision 1.19  2002/07/24 18:45:43  Flayra
// - Linux and scripting changes
//
// Revision 1.18  2002/07/23 17:26:49  Flayra
// - Siege don't require a nearby turret factory, only add built buildings for range detection, build problems on client (point contents failing on rough surfaces)
//
// Revision 1.17  2002/07/08 17:17:44  Flayra
// - Reworked colors, moved functions into server util
//
// Revision 1.16  2002/07/01 21:46:39  Flayra
// - Added support for generic building ranges, fixed morphing problems
//
// Revision 1.15  2002/05/23 02:33:20  Flayra
// - Post-crash checkin.  Restored @Backup from around 4/16.  Contains changes for last four weeks of development.
