$last_curve_style calls for a context for the primitive, ie which was the state of the dataset/curve stack at the moment when the primitive was drawn ?.

TODO:
Maybe this cumbersome level/point thing along with the
$last_curve_style calls for a context for the primitive, ie which was the state of the dataset/curve stack at the moment when the primitive was drawn ?
Worse, I already designed something better. I’ll need to get that straight some day.
