Implement filmic color grading. (#13121) This commit expands Bevy's existing tonemapping feature to a complete set of filmic color grading tools, matching those of engines like Unity, Unreal, and Godot. The following features are supported: * White point adjustment. This is inspired by Unity's implementation of the feature, but simplified and optimized. *Temperature* and *tint* control the adjustments to the *x* and *y* chromaticity values of [CIE 1931]. Following Unity, the adjustments are made relative to the [D65 standard illuminant] in the [LMS color space]. * Hue rotation. This simply converts the RGB value to [HSV], alters the hue, and converts back. * Color correction. This allows the *gamma*, *gain*, and *lift* values to be adjusted according to the standard [ASC CDL combined function]. * Separate color correction for shadows, midtones, and highlights. Blender's source code was used as a reference for the implementation of this. The midtone ranges can be adjusted by the user. To avoid abrupt color changes, a small crossfade is used between the different sections of the image, again following Blender's formulas. A new example, `color_grading`, has been added, offering a GUI to change all the color grading settings. It uses the same test scene as the existing `tonemapping` example, which has been factored out into a shared glTF scene. [CIE 1931]: https://en.wikipedia.org/wiki/CIE_1931_color_space [D65 standard illuminant]: https://en.wikipedia.org/wiki/Standard_illuminant#Illuminant_series_D [LMS color space]: https://en.wikipedia.org/wiki/LMS_color_space [HSV]: https://en.wikipedia.org/wiki/HSL_and_HSV [ASC CDL combined function]: https://en.wikipedia.org/wiki/ASC_CDL#Combined_Function ## Changelog ### Added * Many new filmic color grading options have been added to the `ColorGrading` component. ## Migration Guide * `ColorGrading::gamma` and `ColorGrading::pre_saturation` are now set separately for the `shadows`, `midtones`, and `highlights` sections. You can migrate code with the `ColorGrading::all_sections` and `ColorGrading::all_sections_mut` functions, which access and/or update all sections at once. * `ColorGrading::post_saturation` and `ColorGrading::exposure` are now fields of `ColorGrading::global`. ## Screenshots ![Screenshot 2024-04-27 143144](https://github.com/bevyengine/bevy/assets/157897/c1de5894-917d-4101-b5c9-e644d141a941) ![Screenshot 2024-04-27 143216](https://github.com/bevyengine/bevy/assets/157897/da393c8a-d747-42f5-b47c-6465044c788d)
