Re-asking this question.  In PS and SVG, will the thickness of a curve always 
be added perpendicularly in both directions to the line tangent to the curve at 
a given point?  Also, with rounded caps, does the radius of this cap sweep 180 
degrees starting and ending at the perpendicular axis to the curve while being 
anchored at the beginning and end point?  If so, I can get rid of 
Translate_scale_rotate.
