Three things govern this order:
1. Data are rendered in the order in which they were passed
to DisplayImpl.addReference() or DisplayImpl.addReferences().
2. In a DisplayImplJ2D, renderinsg with images and polygons
are done before renderings with points and lines, so that
for example map outlines are visible over images.
3. In a DisplayImplJ3D with TwoDDisplayRendererJ3D, renderings
with points and lines are located slightly in front of
renderings with images and polygons, for the same motive as
item 2.
Cheers,
Bill
