New cvar, vid_preservegamma. Set it to 0 to obliterate your old gamma settings when you leave FTE. This mimics the use of quake3 to reset your gamma settings should FTE crash on you. The default is to restore gamma settings to how they were when you first loaded FTE, the same as before. You can now use FTE to reset your gamma if FTE crashed and broke it. Only applies to the windows version so far.
