quadraticCurveTo method
This creates a quadratic curve from the currentPath's offset to x and y with cpX and cpY as control point and updates the currentPath's offset to x and y.
Implementation
ShapePath quadraticCurveTo(double aCPx, double aCPy, double aX, double aY) {
currentPath.quadraticCurveTo(aCPx, aCPy, aX, aY);
return this;
}
