	///	a float). A rating of 0 means very good/default (read: Nvidia), while, say, 
	///	a 9.0 (i.e. shift the scale 9 times above normal) means s****y, like, say, 
	///	a Savage4. Also also included is a forced value for max # of layers (0 means 
	///	to use default). Also also also included is an LOD rating indicating how much 
	///	(and in which direction) to alter the base LOD bias value for this device. General
	///	interpretation of this value is to add (-lodRating) to the LOD bias value.
	///	This is because the LOD bias starts out negative and typically goes in 0.25
	///	increments.
	/// Also also ALSO included are three new values for fog tweaking. The first two--
	///	fFogExp/Exp2ApproxStart, are the start of the linear approximation of exponential
	///	fog. Tweak these to adjust the linear approximation on any cards that don't support
	///	exponential and exponential-squared fog natively. The third value is the fFogEndBias--
	///	this is a value (stored as a percentage of the max possible fog value) to add on to
	///	to the linear fog-end parameter AFTER ALL CALCULATIONS. This is so we can, for
	///	example, tweak the end of the fog on the ATI Rage cards to not fog out as quickly.
	///	9.14.2000 - fog end bias now has a new meaning. What it *really* represents is the
	/// quantization of fog on a particular card, where the end bias = ( 2^bitdepth - 2 ) / ( 2^bitdepth - 1 )
	/// So, for 8 bit fog, we end up with 254 / 255, etc. So far, everything is set to 8
