[PyMOL] vrml broken normals

normals appear to be still broken in VRML export. I have attached a
simple test case that demonstrates this. The pdb file attached
contains 1 atom at the origin. To reproduce the wrl file that I have
attached, set the quality to best performance, turn on surface
rendering of the molecule and export the wrl file. The resulting wrl
file clearly has wrong normals both looking at it by hand an opening
it up in deep exploration version 5 and looking at the normals.

This is with the latest incentive build on OS X.
