The locus is the set of points comprising the drawn primitive (it's a term 
I dredged up from my memory of some old math courses -- I hope I got it 
right).  "Abstract locus" means that things like line width are not 
included, but rather only the point positions as if the item were drawn 
with an abstract, infinitely fine pen.

No.  The control points are part of the defining data, but not part of the 
drawn primitive.
