wizdraw - tiny no_std crate to fill and stroke bezier curves

Example

```rust use vek::bezier::CubicBezier2; use vek::vec::Vec2;

// these coordinates correspond to pixels let start = Vec2::new(25.0, 50.0); let curve1 = CubicBezier2 { start, ctrl0: Vec2::new(25.0, 25.0), ctrl1: Vec2::new(75.0, 25.0), end: Vec2::new(75.0, 50.0), }; let curve2 = CubicBezier2 { start: Vec2::new(75.0, 60.0), ctrl0: Vec2::new(75.0, 40.0), ctrl1: Vec2::new(25.0, 40.0), end: Vec2::new(25.0, 60.0), };

let mut points = Vec::new();

// convert the curves to a path; wizdraw::pushcubicbeziersegments::<_, 6>(&curve1, 0.2, &mut points); wizdraw::pushcubicbeziersegments::<_, 6>(&curve2, 0.2, &mut points);

// close the loop points.push(start);

// create a buffer to hold the mask let masksize = Vec2::new(100, 100); let mut mask = vec![0u8; masksize.product()];

// if you want to fill the path: // (SSAA = 4) wizdraw::fill::<_, 4>(&points, &mut mask, mask_size);

// or if you'd like to stroke the path: // (SSAA = 4) let strokewidth = 2.0; wizdraw::stroke::<_, 4>(&points, &mut mask, masksize, stroke_width); ```
