+/* FFB fog support:
+ *
+ * There are two levels of support for FOG in the Creator3D series.
+ * Both involve a depth cue unit and 1 or 4 slope factors and scales
+ * for varying the pixel intensity.
+ *
+ * Chips prior to FFB2 only have a single set of such settings, FFB2
+ * and later have 4 settings.
+ *
+ * The basic depth cueing equation is:
+ *
+ * C_final = dcsf(z) * C_orig + (1 - dcsf(z)) * C_fog
+ *
+ * C_final -- The final color passed to blend unit or frame
+ * buffer (if blending is disabled).
+ *
+ * C_orig -- The color we start with, which comes either from
+ * the raster processor or cpu writes to the smart
+ * framebuffer aperture.
+ *
+ * C_fog -- This is the "fog" color, ie. the desired color
+ * at the deepest Z.
+ *
+ * dcsf(z) -- The depth cue scale as a function of Z.
+ *
+ * With pre-FFB2 chips there are four parameters to control the depth
+ * cue scaling. Here is a diagram:
+ *
+ * 1.0 -------------
+ * | | | |
+ * | | | |
+ * Sfront XXXXX---+---+
+ * | |X | |
+ * dcsf(z) | | X | |
+ * | | X| |
+ * Sback +---+---XXXXX
+ * | | | |
+ * 0.0 -------------
+ * 0.0 Zf Zb 1.0
+ *
+ * z
+ * Therefore:
+ *
+ * for Zf < z < Zb
+ *
+ * dcsf(z) = Sback + ((Sfront - Sback) / (Zf - Zb)) * (Zb - z)
+ *
+ * for z <= Zf
+ *
+ * dcsf(z) = Sfront
+ *
+ * for z >= Zb
+ *
+ * dcsf(z) = Sback
+ *
+ * With FFB2 and later, 3 more slope regions are provided, the first of
+ * them starts at the end of the region defined above and ends at a
+ * specified depth value, the next slop region starts there and ends
+ * at the next specified depth value, and so on. Each of the 3 slope
+ * regions also have scale and slope settings of their own.
+ *
+ * The C_fog color is programmed into the alpha blending unit color1
+ * and color2 registers as follows:
+ *
+ * color1: -(C_fog)
+ * color2: C_fog - bg
+ *
+ * If alpha blending is disabled, the bg factor is zero. Note that
+ * the alpha blending color registers specify each of the RGB values
+ * as 9 bit 1:8 signed numbers in the range -1.00 to 0.ff inclusive.
+ * (ie. 0x100 == -1.00 and 0x0ff == +0.ff)
