 * [ToneMappingEffect](https://engine.needle.tools/docs/api/ToneMappingEffect) adjusts the brightness and contrast of the rendered scene to map high dynamic range (HDR) colors to a displayable range.
 * This effect is essential for achieving realistic lighting and color representation in 3D scenes, as it helps to preserve details in both bright and dark areas.
 * Various tonemapping algorithms can be applied to achieve different visual styles and effects.
