// GameSettings.cpp
// Project: Postal
//
// History:
//		03/31/97 JMI	Started.
//
//		03/31/97	JMI	Moved CGameSettings implementation from game.h to this 
//							file.
//
//		03/31/97	JMI	Now loads game play keys from prefs file.
//
//		04/07/97	JMI	Added m_szServerName and m_usServerPort.
//
//		04/08/97	JMI	Added m_szPlayerName and m_sPlayerColorIndex.
//
//		04/08/97	JMI	Changed defualt for m_usServerPort from 9999 to 61663.
//
//		04/11/97	JMI	No longer sets m_sClient and m_sServer in PreDemo().
//
//		04/14/97	JMI	Added TEMP flag m_bDontBlit to allow us to speed up the
//							Snap() call by not blitting.
//
//		04/21/97 MJR	Added m_pszRealm for the name of the realm prefs file.
//
//		04/22/97	JMI	Added m_sCanRecordDemos indicating something obscure.
//
//		05/15/97	JMI	Added m_sAlphaBlend and m_sXRayEffect.
//
//		05/19/97	JMI	Added m_sDisplayInfo.
//
//		05/22/97	JMI	Added m_s3dFog.
//
//		05/22/97	JMI	Added m_sParticleEffects.

//
//		06/09/97	JMI	Added m_sCanTakeSnapShots.
//
//		06/09/97	JMI	Added m_sCrossHair.
//
//		06/11/97	JMI	Added m_szDontShowTitles.
//
//		06/12/97 MJR	Renamed m_pszRealm to m_pszRealmPrefsFile.
//							Removed m_sServer and m_sClient and m_sDemo.
//							Everything now sets defaults in constructor instead of
//							some things doing it in the Load() portion.
//
//		06/13/97 MJR	Removed m_bDontBlit and cleaned up the loads and saves
//							and made sure everything defaulted properly.
//
//		06/16/97 MJR	Added m_pszDemoMovie.
//							Added m_sNetGetInputInterval
//							Added m_sNetSendInputInterval.
//							Added m_sNetMaxFrameLag.
//							Added m_sNetTimePerFrame.
//
//					MJR	Added m_lNetMaxBlockingTime.
//							Added m_sNetUsersMaxPlayers;
//
//					JMI	Added m_sTrickySystemQuit.
//
//		06/17/97 MJR	Added m_lNetForceAbortTime.
//
//					MJR	Modified to call newer version of CorrectifyBasePath().
//
//		06/19/97	JMI	Added m_sResetMPScoresEachLevel.
//
//		06/23/97	JMI	Added m_szSynchLogFile.
//
//		07/07/97	JMI	Added m_dGameFilmScale and m_dEditorFilmScale.
//
//		07/07/97	JMI	Removed m_dEditorFilmScale and added m_sEditorViewWidth
//							and m_sEditorViewHeight.
//
//		07/08/97 MJR	Added use of separate section ("MacPaths") for mac paths.
//
//		07/16/97	JMI	Changed m_lTitleLoadLoops to m_lTitleDuration.
//
//		07/17/97	JMI	Now saves and loads volume category settings.
//
//		07/20/97	JMI	Added m_sVolumeDistance and m_sGripZoneRadius.
//							Also, now saves m_sDisplayInfo.
//
//		07/23/97 BRH	Changed title durations so that each title screen
//							can have its own duration time rather than splitting
//							it up evenly across all title screens.
//
//		08/03/97 BRH	Added m_usProtocol to be loaded and saved in the ini
//							file.
//
//		08/04/97	JMI	Added m_sPlayAmbientSounds.
//
//		08/05/97	JMI	Added m_eNetConnectionType and 
//							ms_apszNetConnectionTypeNames[].
//
//		08/11/97 MJR	Added m_szHostName and modified connection types and text.
//
//		08/13/97	JMI	PreDemo() now uses difficulty level 10.
//
//		08/18/97 MJR	Lots of changes to network-related stuff.
//
//		08/20/97 BRH	Added Sound, Game and Hoods paths to give more 
//							installation options.
//
//		08/23/97	JMI	Added ms_apszPlayerColorDescriptions[] to provide color
//							descriptions and ms_sNumPlayerColorDescriptions.
//
//		08/24/97	JMI	Editor width and height now default to 640 and 480.
//
//		08/25/97	JMI	Changed some of the color descriptors.
//
//		08/25/97	JMI	Now includes the m_eCurSoundQuality enum representing the
//							game's current sound quality.
//							Also, now sets all the default volumes to one value and
//							stores all values from 0 to the UserMaxVolume instead of
//							in the 0..MaxVolume scale samplemaster uses.
//
//		09/06/97 MJR	Clamped net values to valid ranges.
//
//		09/07/97 MJR	Now defaults to 2 for network lag.
