//! Linear algebra and other useful mathematics.
//!
//! Includes [vectors][self::vec], [matrices][mat], [colors][color],
//! [angles][angle], [Bezier splines][spline] and [pseudo-random numbers][rand],
//! as well as support for custom [varying][vary] types and utilities such as
//! approximate equality comparisons.
//!
//! This library is more strongly typed than many other similar math libraries.
//! It aims  to diagnose at compile time many errors that might otherwise only
//! manifest as graphical glitches, runtime panics, or even – particularly in
//! languages that are unsafe-by-default – undefined behavior.
//!
//! In particular, vectors and colors are tagged with a type that represents
//! the *space* they're embedded in, and values in different spaces cannot be
//! mixed without explicit conversion (transformation). Matrices, similarly,
//! are tagged by both source and destination space, and can only be applied
//! to matching vectors. Angles are strongly typed as well, to allow working
//! with different angular units without confusion.
