[x3d-public] Here's something worth tracking down Roy

[Nicholas Polys]

HI all~

this is important in geo processing pipelines since tools like meshlab can
calculate normals on point clouds,
so they should be legal in the standard IMO
also

we NEED point properties or sprites for better visualization
eg
http://svn.xj3d.org/xj3d_code/trunk/parsetest/xj3d_extensions/pointsprites/

or ParticleSet
