/// Render pass that applies a bloom effect to bright areas of the image.
///
/// Extracts bright pixels above a threshold, blurs them, and outputs them to a separate render target.
/// This render target can then be combined with the original image to create a glow effect which is typically done in the tone mapping pass.
/// Supports configurable radius, threshold, intensity, and tint colors for inner, mid, and outer bloom regions.
