Comment:

 I think I'm making good progress.  I can see my sample TINS and polyhedral
 surfaces, linestring in freeWrl.  Still have to flesh out geometry
 collections, fix polygons, and multilinestrings and figure out how to
 handle holes.

 Also I think X3D convention is X3D x => PostGIS x,  X3D y => PostGIS Z and
 X3D z=> PostGIS Y or something like that. I'm not sure how baked in that
 rule is but I find it mighty confusing so haven't bothered flipping
 things.

 Also have some preliminary documentation in place for those who want to
 give it a wrl

 http://www.postgis.org/documentation/manual-svn/ST_AsX3D.html

 After I get the linestring, polygon stuff somewhat working will work on
 the cunit tests and sql tests.

 It also seems that there are X3D parallel types for our curved geometries
 (in the form of Arc2D, ArcClose2D, Circle2D, and Nurbs).  FreeWrl doesn't
 support Nurbs yet so won't use that.

 http://freewrl.sourceforge.net/conformance.html

 so might be able to throw in curved support too if I can figure out (or
 someone else wants to figure out) how that works or we can save for 2.1
