AgX tonemapping curve, the default view transform of Blender since version 4.0. Bright,
saturated colors desaturate towards white, and the result is lower in contrast and saturation
than TONEMAP_ACES2. This neutral, flat look is often used as a base for color grading.
See TONEMAP_AGX_PUNCHY for a higher contrast version. Based on Filament's implementation
of Blender's AgX.
