impeller-core 0.1.0

//! The public API: what an application draws with.
//!
//! Everything below this — tessellation, batching, backends, presentation — is
//! reachable but not usually reached for. A caller describes a frame on a
//! [`Canvas`] and hands the resulting [`Recording`] to a target.
//!
//! Recording is deliberately separate from submitting. Describing a whole frame
//! before any of it reaches the GPU is what lets draws share a single pass, and
//! it keeps the API free of the question of when work is flushed.
//!
//! Color is linear throughout, converted at this boundary. Blending,
//! filtering, and antialiasing all average colors, and averaging sRGB-encoded
//! values is visibly wrong — see [`Color`].
