A pure Rust 2D Graphics Library.

Raqote aims to be a small, simple, fast software 2D graphics library with roughly the same capabilities as the cairo image backend.

Current functionality - path filling - stroking - dashing - image, solid, and gradient fills - rectangular and path clipping

Planned functionality - layers - blend modes - perspective image drawing - shadows?

Example: ```rust

 let mut dt = DrawTarget::new(400, 400);

 let mut pb = PathBuilder::new();
 pb.move_to(100., 10.);
 pb.cubic_to(150., 40., 175., 0., 200., 10.);
 pb.quad_to(120., 100., 80., 200.);
 pb.quad_to(150., 180., 300., 300.);
 pb.close();
 let path = pb.finish();

 let gradient = Source::RadialGradient(
     Gradient {
         stops: vec![
             GradientStop {
                 position: 0.2,
                 color: 0xff00ff00,
             },
             GradientStop {
                 position: 0.8,
                 color: 0xffffffff,
             },
             GradientStop {
                 position: 1.,
                 color: 0xffff00ff,
             },
         ],
     },
     euclid::Transform2D::create_translation(-150., -150.),
 );
 dt.fill(&path, &gradient, Winding::NonZero);

 let mut pb = PathBuilder::new();
 pb.move_to(100., 100.);
 pb.line_to(300., 300.);
 pb.line_to(200., 300.);
 let path = pb.finish();

 dt.stroke(
     &path,
     &StrokeStyle {
         cap: LineCap::Round,
         join: LineJoin::Round,
         width: 10.,
         mitre_limit: 2.,
         dash_array: vec![10., 18.],
         dash_offset: 16.,
     },
     &Source::Solid(SolidSource {
         r: 0x0,
         g: 0x0,
         b: 0x80,
         a: 0x80,
     }),
 );

 dt.write_png("example.png");
