/// a 9.0 (i.e. shift the scale 9 times above normal) means s****y, like, say,

/// 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
