Create ArcPathElement2d and ArcPathElement2dfx

[sebpetit]

The constructors can be :
ArcPathElement2fp(double fromx, double fromy, double radiusx, double radiusy, double tox, double toy)
ArcPathElement2fx(DoubleProperty fromx, DoubleProperty fromy, DoubleProperty radiusx, DoubleProperty radiusy, DoubleProperty tox, DoubleProperty toy)

The creation of these path elements will be done through the following function on paths:

• arcTo(double ctrlx, double ctrly, double radiusx, double radiusy, double tox, double toy)
• arcTo(double radiusX, double radiusY, double ellipseRotation, boolean largeArc, boolean sweepArc, double tox, double toy)

No new path element type will be created since the arcTo functions are invoking the curveTo function.

Is it possible to create an ArcPathElement2fx in PathElement2dxf to differentiate it from CurvePathElement2fx ?

In FXTL, in PathShape2D, we need to know when a PathElement2dfx has an ARC_TO type to create an ArcTo JavaFX object. We create a CubicCurveTo JavaFX object when a PathElement2dfx has a CURVE_TO type.

The JavaFX Path2D is creating a curve when its arcTo function is called. It means that a JavaFX Path2D never replies ArcTo path elements. Indeed, ArcTo path element exists in JavaFX, but is is created only by the PieChart region.

However, I may add this new type of path element, that will be at the end mapped to a curve.
