Bastien Montagne 5e32dc0efb Fix T49420: X3D Exporter generates duplicate edges and splits the mesh when exporting with Triangulate.
No point in splitting vertices over small differences in UVs or Color
values.

Note that there will still be splits when those UVs or colors actually
do not match, but this seems to be part of 'triangulated' export design
(otherwise we could use indexed values as with regular polygons export).

Based on investigation by Sebastian Ullrich (@souljedi), thanks.
