flo_draw

flo_draw is a crate for Rust that aims to make it as easy to draw 2D graphics on screen as it is to call println! to write some text to a terminal. It's based on the 2D primitives defined in flo_curves, and it relies heavily on the lyon and glutin crates for tesselation and window management.

Here's a simple example that will open up a window with a triangle in it:

```Rust use flodraw::*; use flocanvas::*;

pub fn main() { with2dgraphics(|| { let canvas = createcanvaswindow();

    canvas.draw(|gc| {
        gc.clear_canvas(Color::Rgba(0.0, 0.0, 0.0, 1.0));
        gc.canvas_height(1000.0);
        gc.center_region(0.0, 0.0, 1000.0, 1000.0);

        // Draw a rectangle...
        gc.new_path();
        gc.move_to(0.0, 0.0);
        gc.line_to(1000.0, 0.0);
        gc.line_to(1000.0, 1000.0);
        gc.line_to(0.0, 1000.0);
        gc.line_to(0.0, 0.0);

        gc.fill_color(Color::Rgba(1.0, 1.0, 0.8, 1.0));
        gc.fill();

        // Draw a triangle on top
        gc.new_path();
        gc.move_to(200.0, 200.0);
        gc.line_to(800.0, 200.0);
        gc.line_to(500.0, 800.0);
        gc.line_to(200.0, 200.0);

        gc.fill_color(Color::Rgba(0.0, 0.0, 0.8, 1.0));
        gc.fill();
    });
});

} ```

flo_draw provides an independent implementation of the rendering system used by FlowBetween, a project to develop a vector animation editor. It was created to assist in debugging: often it's much easier to draw a diagram, but until now it's been quite involved to write a program to tell a computer to do that.
