 Huge credit to @StarLederer, who did almost all of the work on this. We're just reusing this PR to keep everything in one place. # Objective 1. Make bloom more physically based. 1. Improve artistic control. 1. Allow to use bloom as screen blur. 1. Fix #6634. 1. Address #6655 (although the author makes incorrect conclusions). ## Solution 1. Set the default threshold to 0. 2. Lerp between bloom textures when `composite_mode: BloomCompositeMode::EnergyConserving`. 1. Use [a parametric function](https://starlederer.github.io/bloom) to control blend levels for each bloom texture. In the future this can be controlled per-pixel for things like lens dirt. 3. Implement BloomCompositeMode::Additive` for situations where the old school look is desired. ## Changelog * Bloom now looks different. * Added `BloomSettings:lf_boost`, `BloomSettings:lf_boost_curvature`, `BloomSettings::high_pass_frequency` and `BloomSettings::composite_mode`. * `BloomSettings::scale` removed. * `BloomSettings::knee` renamed to `BloomPrefilterSettings::softness`. * `BloomSettings::threshold` renamed to `BloomPrefilterSettings::threshold`. * The bloom example has been renamed to bloom_3d and improved. A bloom_2d example was added. ## Migration Guide * Refactor mentions of `BloomSettings::knee` and `BloomSettings::threshold` as `BloomSettings::prefilter_settings` where knee is now `softness`. * If defined without `..default()` add `..default()` to definitions of `BloomSettings` instances or manually define missing fields. * Adapt to Bloom looking visually different (if needed).
