Allen Pestaluky 0c7f013c55 Improve Environment color adjustments; specifically brightness and HDR 2D contrast. 
This commit changes adjustments to behave as follows for all rendering configurations:

- Apply brightness to linear-encoded values, preventing contrast, saturation, and hue from being affected.
- Apply contrast to perceptually uniform (nonlinear sRGB-encoded) values, matching existing behavior when HDR 2D is disabled and producing optimal visual quality.
- Apply saturation with even color channel weights. This causes brightness of certain colors to change, but matches existing behavior when HDR 2D is disabled.

Adjustments are applied after glow and tonemapping to match existing behavior.
