* initial 1.5 import
*
*
* 26 8/16/99 5:38p Jeff
* final updates for patch
*
* 25 8/15/99 4:36p Jeff
* finished exporting all inventory class functions. export object_info
* array. added check for -nooutragelogo to display Outrage logo display.
*
* 24 8/11/99 5:31p Jeff
* addon tablefile function returns a bool now
*
* 23 8/11/99 1:22p Jeff
* exported needed functions for camera windows
*
* 22 7/20/99 11:27a Jeff
* created functions to fire weapons
*
* 21 7/11/99 3:31p Jeff
* exported game arguments, made command line option to specify
* autoexec.dmfc
*
* 20 7/07/99 12:16p Jeff
* all mangles symbol names fixed. Finished making interface functions.
*
* 19 5/20/99 5:31p Jeff
* exported PlayerStopSounds
*
* 18 5/19/99 11:49p Jeff
* final preparations for dmfc version 1.0
*
* 17 5/19/99 5:27p Jeff
* fixed some function prototypes
*
* 16 5/19/99 2:44a Jeff
* CreateTextItem has a third parameter
*
* 15 5/03/99 8:39a Jeff
* tons of Entropy fixes
*
* 14 4/30/99 7:36p Jeff
* exported vis_effects to dmfc
*
* 13 3/27/99 4:53p Jeff
* player rankings in multiplayer games implemented. Fixed join message
* so it doesn't get cut off
*
* 12 3/22/99 6:20p Jeff
* added 2 more audio taunts. a mulitplayer event when someone plays an
* audio taunt. option to disable audio taunts.
*
* 11 3/17/99 12:23p Jeff
* converted DMFC to be COM interface
*
* 10 3/12/99 7:40p Jeff
* removed enhanced objcreate, added enhanced objsetpos
*
* 9 3/11/99 6:30p Jeff
* numerous fixes to demo system in multiplayer games (when
* recording/playback a demo in a multiplayer game)
*
* 8 3/05/99 1:29p Jeff
*
* 7 2/25/99 8:54p Jeff
* Inventory supports level change persistant items. Inventory supports
* time-out objects. Inventory Reset changed (takes a level of reset
* now). Quad lasers stay across level change (single player). Guidebot
* bug fixed (now back in ship on level start). Quads time out when
* spewed. Invulnerability and cloak powerups no longer use game
* event/callbacks, so they can be saved in game saves (moved to
* MakePlayerInvulnerable and MakeObjectInvisible)
*
* 6 2/10/99 11:36p Jeff
* exported renderer and fvi functions
*
* 5 2/08/99 5:22p Jeff
* exported rend_SetZBuffer...fixed up small view of stats
*
* 4 2/08/99 12:06a Jeff
* exported some new functions and variables
*
* 3 2/06/99 6:59p Jeff
* created RenderHUDGetTextLineWidth and RenderHUDGetTextHeight
*
* 2 2/03/99 4:09p Jeff
* moved function pointers to seperate file. created autoexec.dmfc
