[Splines] Flat shape and Curve controls within Renderable Spline Modifier

[Kranos_Orphydian]

We could use a flat shape (ribbon, blade )in render shape as well as some controls (also a Curve graph) to Scale, Rotate, Twist along Shape within the Renderable Spline modifier. It could have far more potential than it has currently.

Same options are needed for Sweep modifier. Upvote the idea here:
