Changes between WinQuake and GoldQuake
Last updated: Feb 17 2010

-------------------------------------------------------------------------------

WINDOWS STUFF
- Don't show the "Starting Quake..." splash screen.

2D RENDERING
- Center the intermission overlay.
- Don't draw crosshair during the intermission.
- Center the crosshair a little more accurately.
- Added "showfps" cvar.
- Implemented a colour tint effect when in the menu, to replace the old black
  "mesh" effect.

CHASE CAMERA
- Fixed the bug where the player model didn't show up in chasecam mode.
- Changed the camera calculation to match DarkPlaces (looks up and down
  properly and doesn't go through walls).
- Removed "chase_right" cvar.

CONSOLE
- Raise/lower the console at a speed as if the screen resolution was 320x200,
  so at high resolutions the console doesn't move really slow.

EXTENSIONS
- DP_ENT_VIEWMODEL (viewmodelforclient)
- DP_INPUTBUTTONS (adds +button3 through +button8)
- DP_QC_MINMAXBOUND
- DP_QC_RANDOMVEC
- DP_QC_SINCOSSQRTPOW
- DP_QC_VECTORVECTORS
- DP_TE_BLOOD
- DP_TE_BLOODSHOWER
- DP_TE_STANDARDEFFECTBUILTINS

GAMEPLAY
- Implemented "sv_gameplayfix_setmodelrealbox" (as seen in DarkPlaces).
  Defaults on. Turn it off to replicate the broken behaviour which some badly
  coded mods might depend on. This fix causes setmodel() calls to set the
  entity's bounding box to its model's bounds, rather than the generic
  '-16 -16 -16', '16 16 16'. This fixes, among other things, the exploboxes
  in Asaki's pak2.pak.
- Changed default value of "sv_aim" cvar to 2, disabling autoaim.
- Implemented MOVETYPE_BOUNCEMISSILE.
- Fixed a rare (or not so rare, in one mod) crash relating to lightning beams.

INPUT
- Added "freelook" cvar (saved to config).
- Removed -dinput mode.
- Fixed the disabling of mouse acceleration. If you want to keep the system
  setting (as vanilla Quake incorrectly did), use the command-line parameter
  "-noforcemparms". The options "-noforcemspd" and "-noforcemaccel" have been
  removed.
- Added support for mouse4 and mouse5 binds.
- Got rid of the "X is not bound" message when pressing unbound mouse/joystick
  buttons.
- The keypad can be used in the console and bound to game actions. The key
  names are identical to those in DarkPlaces and begin with "KP_".
- Added "in_pitch_min" and "in_pitch_max" cvars, which allow you to control how
  far up/down the player can look. Defaults to the original Quake values.

TIMING
- Use timeGetTime instead of QueryPerformanceCounter to avoid timing issues
  on some machines.

VIEWMODEL
- Show gun model even when FOV is not 90.
- r_drawentities 0 will also hide the gun model.
- Don't move the gun model up to stay above the statusbar (you can reenable
  this behaviour with the "v_fudgeweapon" cvar).

PROTOCOL NOTES

Some extensions, when used, use an extended network protocol. This means that
GoldQuake and vanilla Quake won't be able to connect to each other's servers if
(and only if) these extensions are used. Also, demos recorded in GoldQuake
using these extensions won't be playable in vanilla Quake engines.

However, in every case I have made sure to implement the protocol extension
identically to DarkPlaces, which is the closest thing to a standard there is.
So DarkPlaces should be able to connect fine to GoldQuake servers, even using
the extensions.

Extensions which affect the network protocol:

- DP_ENT_VIEWMODEL

Note: DP_INPUTBUTTONS (+button3 through +button8) does NOT change the network
protocol, since it simply uses unused bits in the existing Quake protocol. You
can use this extension without worrying about compatibility issues (the button
events simply won't do anything for users of older engines).
