DrawingPen
Sketchers allow the user to draw a two dimentional shape using segment of
curve. You start by defining where you sketch will start (with the method
movePointerTo.
Each sketching method corresponds to drawing a curve of some type (line,
arc, elliptic arc, bezier curve to a new point. The next segment will start
from the end point of the previous segment.
Once you end your sketch you will receive a Sketch object that allows you
to give some three dimentionlity to your finished sketch.

▸ bezierCurveTo(end, controlPoints): DrawingPen
Draws a generic bezier curve to the end point, going using a set of control points.
This is the generic definition of a bézier curve, you might want to use either the quadratic or cubic (most common) version, unless you know exactly what you are aiming at.

smoothSpline
▸ smoothSpline(xDist, yDist, splineConfig?): DrawingPen
Draws a cubic bezier curve to the end point, attempting to make the line smooth with the previous segment. The end point is defined by its distance to the first point.
It will base its first control point so that its tangent is the same than
the previous segment. You can force another tangent by defining
startTangent.
You can configure the tangent of the end point by configuring the
endTangent, either as "symmetric" to reproduce the start angle, as an
angle from the X axis (in the coordinate system) or a 2d direction (still
in the coordinate system.
The start- and end- factors decide on how far the control point is from the start and end point. At a factor of 1, the distance corresponds to a quarter of the straight line distance.

xDist | number |

smoothSplineTo
▸ smoothSplineTo(end, config?): DrawingPen
Draws a cubic bezier curve to the end point, attempting to make the line smooth with the previous segment.
It will base its first control point so that its tangent is the same than the previous segment.
The control point relative to the end is by default set to be in the
direction of the straight line between start and end. You can specifiy the
endSkew either as an angle (in degrees) to this direction, or as an
absolute direction in the coordinate system (a Point).
The start- and end- factors decide on how far the control point is from the start and end point. At a factor of 1, the distance corresponds to a quarter of the straight line distance.
