repame-view2d 0.3.31

//! 2D viewport: snapshot in, pixels out.
//!
//! The whole 2D screen path of a game lives here, plain sprites included: a
//! game that draws sprite quads over an atlas needs nothing else, and uses
//! [`SpriteInstance`] rows through the instanced [`SpriteBatch`], framed by a
//! dp-space [`Camera2d`] ([`FitMode`]) whose fit law the canvas, the GPU batch
//! and the CPU picks all read from the same functions ([`effective_fit`],
//! [`fit_view_proj`], [`world_to_dp`], [`dp_to_world`]).
//!
//! Around that core:
//!
//! * [`RasterAtlas`] - raster sheets drawn through the same batch, and the
//!   world-anchored [`ActorDrawList`] that puts them, `.ren` vector rigs and
//!   solid rects in one z order.
//! * [`light`] / [`lightpass`] - 2D lighting: point lights with ramped or
//!   textured falloff, Godot's add/sub/mix blend modes, `light_mask` layers,
//!   and polygon occluders casting filtered shadows into a light map that
//!   [`SpriteBatch::set_light_source`] consumes.
//! * [`WorldText`] - world-anchored text floaters, and [`design`] - the design
//!   box onto dp canvas mapping games would otherwise hand-roll.
//! * [`PickEvent`] - presses, hovers and the slop rule behind a click, plus
//!   [`CursorFrame`]s for a hardware cursor.
//! * [`fullscreen`] - the fullscreen post pass hook, driven by a WGSL shader
//!   and per-pass uniforms/textures.
//! * [`actors_view`] - `.ren` rigs played through `renamite-player`, one rig
//!   filling one presented surface.
//!
//! Unit discipline lives here, once: games work in world/dp units and do not
//! touch physical px.
