.Clone() Returns a clone of this spline.
.color Spline's color, if it has been set, 8487555 otherwise.
.CPFracUV(cp.frc) Gives the uv position along the perimeter of the spline, on the current frame. The value cp.frc value is a control point# (integer) plus a fractional [0,1) value towards the next control point.
.ignore Ignore this spline in most algorithms. (Scripts must decide what to do based on their own objectives.)
.invert If nonzero, spline is inverted: what’s in is out, and what’s out is in.
.isDone Spline is done, ie locked.
.isEnabled Spline is enabled or not on each frame, animated
.isEnableKeyed Reports on whether enable is keyed or not, may be written to zero to clear a key.
.nm Spline name
.obj Object assigned to the interior of this spline
.PerimeterUV(frc) Gives the uv position along the perimeter of the spline, on the current frame. The value frc ranges from 0 to 1 around the entire perimeter.
.shot Shot the spline is attached to (read/write).
When the shot is changed, the .obj is cleared, making it a garbage spline, until you change it to a valid object on the new shot.
.show Show/hide the spline in the camera view
.uniqueID A unique ID string (representing a 64-bit integer)
.vtx List of spline vertices
.willDelete Spline is scheduled for deletion
