Pointsets and ISO exports

[npolys]

It would be worthwhile to test the X3D / VRML exporter for this use case:

Several ISSUES:

I loaded a .ply from CloudCompare (originally a .las); it has colors per vertex .

1 = syntax ] for .wrl, a point cloud gets exported as an IndexedFaceSet node (rather than a PointSet)
[ the other attributes like creaseAngle and solid are not needed for PointSets]
In the X3D export, there is a PointSet, but also an empty IndexedFaceSet

2 = data ] wrl and X3D export are broken, with some loop only writing out points in discrete rows.

RE #2
I believe that when exporting a point cloud as a 'mesh',
it is not dumping all the points (colors and normals), only those in discrete rows and columns of x y z
.... this appears to be true for .wrl, .x3d, and .json

.ply export of point clouds w colors and normals seems to work as expected (proven by round-tripping a file)
