Name
CurveTo -- add curve to path (V5.0)
Synopsis
CurveTo(id, x1, y1, x2, y2, x3, y3)
Function
This command will add a cubic Bézier spline curve to the path. The curve will run from the current point to the position specified in x3,y3. The control points of the spline curve have to specified in arguments x1,y1 and x2,y2. When CurveTo() returns, the path's current point will be at x3,y3.

Inputs
id
identifier of path to add curve to
x1
x coordinate of control point #1
y1
y coordinate of control point #1
x2
x coordinate of control point #2
y2
y coordinate of control point #2
x3
x coordinate of curve destination point
y3
y coordinate of curve destination point
