Example

let width = 1280;
let height = 720;

let v0 = Vertex::new(
   [width as f32 / 2.0, 1.0].into(),
   [1.0, 0.0, 0.0, 1.0].into(),
   [0.0, 0.0].into(),
);
let v1 = Vertex::new(
   [1.0, height as f32 - 1.0].into(),
   [0.0, 1.0, 0.0, 1.0].into(),
   [1.0, 0.0].into(),
);
let v2 = Vertex::new(
   [width as f32 - 1.0, height as f32 - 1.0].into(),
   [0.0, 0.0, 1.0, 1.0].into(),
   [1.0, 1.0].into(),
);

let mut canvas = SoftTriCanvas::new(width, height, TextureFormat::RGBA);
canvas.draw_tri(v0, v1, v2, None);

// draw to a window/image using canvas.buffer
