//! 3MF Material Extension types
//!
//! This module provides data structures for the 3MF Material Extension, which enables
//! full-color and multi-material 3D printing workflows.
//!
//! # Key Types
//!
//! - [`ColorGroup`] - Container for color properties (vertex colors)
//! - [`Texture2DGroup`] - Container for texture coordinate properties
//! - [`CompositeMaterials`] - Mixing multiple base materials in defined ratios
//! - [`MultiProperties`] - Layering multiple properties (color + texture + material)
//! - [`Texture2D`] - Image references for texture mapping
//!
//! # Usage
//!
//! Objects reference material resources via the `pid` and `pindex` attributes on triangles.
//! The Material extension provides different ways to represent material properties:
//!
//! - **ColorGroup**: Simple vertex colors in sRGB format
//! - **Texture2DGroup**: UV mapping for bitmap textures
//! - **CompositeMaterials**: Mixing multiple base materials
//! - **MultiProperties**: Layering different property types together
//!
//! # Example XML Structure
//!
//! ```xml
//! <m:colorgroup id="1">
//!   <m:color color="#FF0000" />
//!   <m:color color="#00FF00" />
//! </m:colorgroup>
//! <m:texture2d id="2" path="/3D/texture.png" contenttype="image/png" />
//! <m:texture2dgroup id="3" texid="2">
//!   <m:tex2coord u="0" v="0" />
//!   <m:tex2coord u="1" v="1" />
//! </m:texture2dgroup>
//! ```
