 - Linux OpenGL X11 handling completely rewritten.  Support for XF86DGA Mouse
   and fullscreen resolution support added.  Please see the README file for
   Linux about the new features of this handling.
-
-3.20 Changes:
-- Fixed a network problem where and oversize packet could cause a client 
-  crash.
-- Fixed the long standing Quake2 bug of where you would occasionally spawn
-  or teleport and find yourself either looking straight at the ceiling or
-  down at the floor.
-- Changed it so that the function keys (F1 through F12) now get executed when 
-  depressed during demo playback or attract modes.  This allows you to take 
-  screen shots (F12) during demos and other features.  An example of other 
-  features is a fast forward for demos:
-      alias +ff "timedemo 1"
-      alias -ff "timedemo 0"
-      bind f7 +ff
-  This binding will cause the current demo playing to zip into timedemo mode 
-  while F7 is depressed, effectively acting like a fast forward key.
-- Wrong packaging of 3.19 patch.  The Rogue CD has a 45k pak2 and vwep .md2 
-  files in baseq2/players, but the 3.19 x86 patch we released has a 2.7MB 
-  pak2.  3.20 has a 45k pak2 and the vwep models go in baseq2/players.
-- VWep code has been added to Xatrix dll, new VWep models for the Xatrix 
-  specific weapons (Ion Ripper and Phalanx) have been included.
-- Rogue Linux game library was wrong version and had some unlinked symbols,
-  this has been corrected.
-- Occasional error of: "D_SCAlloc: bad cache width 16384" in software renderer.
-  This had to do with surfaces to SURF_FLOWING and were transparent.  This 
-  has been fixed in the refs now so flowing transparent textures now works.
-- [Unix] Net_ErrorToString calls were wrong, was using %i and not %s resulting
-  in random numbers being printed for error messages.
-- Color shell mixing restored to the same blends as previous versions.  This 
-  was changed in 3.19 for the new color shells the Rogue mission pack 
-  introduced.
-- Fixed a possible server crash in the new "playerlist" command.
-- Fixed a case where a person joining a server could be invisible (left over 
-  setting of SVF_NOCLIENT from previous spectator).
-- Invalid pak files no longer cause a crash and are just ignored
-- Fixed a 3.19 bug where linked models (modelindex2) who's modelindex was 
-  greater than 0x7f causes the wrong model to be drawn (in some cases, the 
-  world would be drawn twice).  This was the cause of many of the "extreme" 
-  frame lag people were seeing in 3.19 on servers using old-style VWep code.
-- Linux:  Complete rewrite of the OpenGL library handling.  This was needed 
-  to cleanly integrate OpenGL extension checking.  Linux now supports 
-  extensions such as multitexture and better dynamic loading of libraries.  
-  It's cleaner now in that you don't have to preload hack stuff to use the 
-  3DFX Miniport rather than libMesa3D.  The Linux version now uses the 
-  gl_driver to specify the 3D library to dynamically load.  For example, to 
-  use the lib3dfxgl.so miniport, one would now use:
-      ./quake2 +set vid_ref gl +set gl_driver lib3dfxgl.so
-  This change fixes several bugs that were apparant in the older method, such 
-  as a segfault occasionally when connecting to a server with a different game 
-  directory.
-  The vid menu in the Linux version has been changed to reflect the new 
-  options, the current list of supported video drivers are now:  software, 
-  software X11, Mesa 3-D 3DFX, 3DFXGL Miniport, OpenGL glX, and Mesa 3-D glX,
-- Railgun shots now go through gibs as well as other players.
-- New server variable, "needpass" that can been seen with server browser
-  tools such as GameSpy.  This variable indicates whether a password or
-  spectator password is needed to get onto a server.  Bit 0 is password and
-  bit 1 is spectator password. 
-- Quake2 will no longer look for gamex86.dll in the main Quake2 directory.
-  It will always load out of the game directory first.
-- Players joining a server during an intermission are now moved to the
-  intermission position.
-- The "logfile" cvar has been extended with the following values:
-	0 - don't log (default)
-	1 - overwrite qconsole.log and use buffered writes
-	2 - overwrite qconsole.log and flush write every line
-	3 - append to existing qconsole.log and flush write every line
-- Several minor bug fixes to the Rogue mission pack gamex86.dll
-- Linux:  Rebuild of Rogue mission pack shared library to correct some
-  dynamic symbol errors (is NAN errors).
