The sample shown represents the edges of the spline as a series of line 
segments, each one drawn separately.  So, the result is that many of the 
pixels are drawn many time.  We'll convert the spline edges into a polygon 
and fill that.

Also, the tolerance when drawing that spline was rather coarse (1 pixel) 
which can generate visible blockiness along the edges; this wouldn't 
affect the thickness of the lines.
