prismatica 0.3.1

//! Macroquad integration.
//!
//! Provides bidirectional conversion between [`Color`](crate::Color)
//! and [`macroquad::color::Color`].
//!
//! Forward conversion sets alpha to 1.0 (fully opaque).
//! Reverse conversion discards the alpha channel.
//!
//! # Examples
//!
//! ```ignore
//! use prismatica::crameri::BATLOW;
//!
//! let color = BATLOW.eval(0.5);
//! let mc: macroquad::color::Color = color.into();
//! let back: prismatica::Color = mc.into();
//! assert_eq!(color, back);
//! ```
