Hi Vanimurarka,

There is one thing you should keep in mind: If you observe
a certain pattern/behaviour like "order of facets",  if it
is not documented, you have no guarantee that a future
release does not change it.   This is not a hypothetical
statement : We had such a change for the triangulations,
where you can insert a range of points. From one release
to another we internally reordered them, which broke code
of users who before exploited that we did not order.

Bottomline: only rely on the spec ( = Reference Manual)

Best regards,

andreas
