stroke.rotate
Property; a string that specifies the rotation of a hatch line. This property is available only if the stroke.style property is set to hatched (see stroke.style). Acceptable values are "none", "slight", "medium", and "free".
The following example sets the rotate property to free for a style stroke of hatched:
var myStroke = fl.getDocumentDOM().getCustomStroke();
myStroke.style = "hatched";
myStroke.curve = "straight";
myStroke.space = "close";
myStroke.jiggle = "wild";
myStroke.rotate = "free";
myStroke.length = "slight";
myStroke.hatchThickness = "thin";
