  /**
   * Calculates the coordinates of a point at a certain `position` on the Rectangle's perimeter.
   * 
   * The `position` is a fraction between 0 and 1 which defines how far into the perimeter the point is.
   * 
   * A value of 0 or 1 returns the point at the top left corner of the rectangle, while a value of 0.5 returns the point at the bottom right corner of the rectangle. Values between 0 and 0.5 are on the top or the right side and values between 0.5 and 1 are on the bottom or the left side.
