Dimensions are not known explicitly from the 3D Artwork.
\useexternalfigure allows us to set height and width as desired.
Moreover, for  a given width, different height doesn't affect the aspect

What do you mean by "pluggable" ? Do you mean that we can turn this
"feature" on or off ? (for the moment, it's definitely off ;)  )
