# Purpose : The thickness and the color of the strokes vary continuously
# independently from occlusions although only
# visible lines are actually drawn. This is equivalent
# to assigning the thickness using a parameterization covering
# the complete silhouette (visible+invisible) and drawing
# the strokes using a second parameterization that only
# covers the visible portions.
