// Revision 1.11  2002/09/25 20:52:34  Flayra
// - Refactoring
//
// Revision 1.10  2002/08/31 18:01:03  Flayra
// - Work at VALVe
//
// Revision 1.9  2002/07/23 17:34:59  Flayra
// - Updates for new hive sight info
//
// Revision 1.8  2002/07/08 17:21:57  Flayra
// - Allow up to 64 blips, don't ASSERT if we exceed them (trying to draw all physents from shared code on client and server)
//
// Revision 1.7  2002/07/01 21:22:09  Flayra
// - Reworked sprites to be simpler and to allow more types
//
// Revision 1.6  2002/06/10 20:04:39  Flayra
// - Blip list wasn't being cleared properly (?)
//
// Revision 1.5  2002/05/28 18:13:02  Flayra
// - New hive sight (different states for different targets)
//
// Revision 1.4  2002/05/23 02:32:57  Flayra
// - Post-crash checkin.  Restored @Backup from around 4/16.  Contains changes for last four weeks of development.
