IMHO a mosaic can't replace true vectors or poligons. regardless of the
resolution you will still need an obcene amount of quads to define the shapes.
it won't be the giant leap but it would be the small step if the LSC could with
a new linetype describing poligons. still human readable they would fulfill the
most wanted requirement for ldraw.
