awsm-renderer 0.4.1

//! Shadow mapping subsystem.
//!
//! The `Shadows` struct sits on [`AwsmRenderer`](crate::AwsmRenderer)
//! and owns every GPU resource needed for shadow generation and
//! sampling: a 2D PCF/PCSS atlas, an RGBA16F EVSM atlas (allocated
//! lazily), a depth cubemap-array slot pool for point lights, the
//! descriptor uniform buffer that the material-opaque shading pass
//! reads at sample time, and the depth-only render pipeline used for
//! shadow generation.
//!
//! This file is module wiring only — the actual implementation lives
//! in named siblings (`state`, `helpers`, `consts`, `record`, `api`).
