Oops! You are correct. Yes, I was thinking of the *possible* change that 'srgb'
might make to the black-to-white fog gradient. But as you say, rgb and srgb look
the same.

I must have been thinking instead about the effects that the newer blend_mode
and blend_gamma keywords have on a color_map. But simple fog cannot use a
color_map, unfortunately.
