8/// Static led material.
9///
10/// It lets you add emission to material or make it like transparent like glass.
11///
12/// # Examples:
13///
14/// For the effect from the examples:
15///
16/// ```rust
17/// LEDMaterial::default();
18/// ```
19///
20/// You can specify your own color and emission intensity of cource:
21///
22/// ```rust
23/// LEDMaterial::new(Color::WHITE).with_emission(3.0);
24/// ```
