/// Example:
|
|
/// ```cpp
|
|
/// LinearGradient()
|
|
/// .Angle(45)
|
|
/// .Stop(Color::Red, 0.0)
|
|
/// .Stop(Color::Green, 0.5)
|

/// .Stop(Color::Blue, 1.0);
|

/// ```

/// ```cpp
|
|
/// LinearGradient(Color::Red, Color::Blue);
|
|
/// LinearGradient(45, Color::Red, Color::Blue);
|
|
/// ```
