Joost De Cock b34a2ee2ed feat: Flat import of markdown repo
This is a flat (without history) import of (some of) the content
from our markdown module.

We've imported this without history because the repo contains our
blog posts and showcases posts content prior to porting them to strapi.

Since this contains many images, it would balloon the size of this repo
to import the full history.

Instead, please refer to the history of the (archived) markdown repo
at: https://github.com/freesewing/markdown

200|Shaping the straps

Nos attaches devraient suivre l'encolure, ce qui n'est pas difficile à faire. Il nous faut juste nous assurer que les points de contrôle de nos courbes aient des proportions similaires. Ce qui signifie, à la moitié entre le début de la courbe et le coin de notre rectangle.

For this, you'll be using a new method: Point.shiftFractionTowards(). We've already used Point.shift() and there's also Point.shiftTowards() and Point.shiftOutwards(). As always, the API docs have all the details.

points.edgeLeft = new Point(points.topLeft.x, points.left.y);
points.edgeRight = new Point(points.topRight.x, points.right.y);
points.edgeTop = new Point(0, points.topLeft.y);

points.edgeLeftCp = points.edgeLeft.shiftFractionTowards(points.topLeft, 0.5);
points.edgeRightCp = points.edgeLeftCp.flipX();
points.edgeTopLeftCp = points.edgeTop.shiftFractionTowards(
  points.topLeft,
  0.5
);
points.edgeTopRightCp = points.edgeTopLeftCp.flipX();

Maintenant, adaptons notre chemin rect de façon à ce qu'il ne soit plus un rectangle :

paths.rect = new Path()
  .move(points.edgeTop)
  .curve(points.edgeTopLeftCp, points.edgeLeftCp, points.edgeLeft)
  .line(points.bottomLeft)
  .line(points.bottomRight)
  .line(points.edgeRight)
  .curve(points.edgeRightCp, points.edgeTopRightCp, points.edgeTop)
  .close();

Tout à coup, les choses commencent à prendre la forme d'un bavoir :
