Drawing complex shapes: B├ęzier and quadratic curves

You can actually get fairly advanced with some of the drawing operations that are possible with the canvas. In fact, the canvas lets you draw Bezier and quadratic curves. The way curves are drawn is in the case of Bezier curves, there is a starting context point, and an end point that uses two what are called control points to determine how the curve is drawn. Quadratic curves are similar. They use a start point, but they only have one control point and one endpoint.

So Bezier curves because of those two control points, they let you draw curves that are slightly more complex. So let's take a look at each one. The Bezier curve has a starting point, which is right here, the context point. That's the end point right there. And there are these two control points. These two control points control how the line curves towards the control point in each case. So you can see that because this end point is close to its control point, the curve is a little bit different over here than it is ove...
