Trying to modify the zwritemask (to 0x0) for entire branches of the
database tree we found that Performer re-enables the z-writing
(for example while drawing light points or transparent geometry).

So I have the following questions:

1) Can I tell Performer to keep the zwritemask at the given state?

2) Is there a list of Performer functions where zwritemask is switched?

3) In those functions, is the zwritemask switched at the end of the
   function or somewhere in the middle?
   If the latter is true I think I have to avoid such geometry !
   For the first I would have to live with zwritemask(0x0)'s in
   all (critical) post draw callbacks.

Thanks in advance,
