Returns the current pen angle in degrees
The angle represents the tangent direction at the current pen position, based on the last drawing operation (line, arc, bezier, etc.). Returns 0 if nothing has been drawn yet.
Returns the current pen position as [x, y] coordinates

Protected_Require that a previous curve exists, returning it or throwing.
Protected_Resolve a relative offset from the current pointer position.

DrawingPen is a helper class to draw in 2D. It is used to create drawings by exposing a builder interface. It is not a drawing itself, but it can be used to create a drawing.
