Excuse me, but I am slowly getting upset you continue to fail to take this
off the list.  There is no point in keeping a list of bugs if you keep
things on there that have been explained as user errors several times...

perhaps nothing important but your comment in () is mistaken becouse in original
post it sounds "looks like a 'coincident surfaces' type of problem, though of
course it is not."

Tracking these was a bit of a nightmare because some of them arrived on
my newserver with completely different subject lines and subtly
different message ids. I can search my article database by either of
those fields, or by author (but you wrote so many!).

Original Subject: crash during function creation in loop

Isn't this already reported in the thread that Thorsten referred you to?

OK


>Function declaration and namespace

I got totally confused by this thread, and can't seem to see if anything
ever actually got confirmed, and if so, what.

>Wrong highlighting in editor (function_id)
>http://news.povray.org/jfji3ug1faevn1jk3mlko64sb71ptmmn97%404ax.com

Unconfirmed

>Splines - not working legal statement
>http://news.povray.org/m7fq3u41ctia9e6i3tbnlstn6ek739vpke%404ax.com

Original Subject: splines - documentation and reality

I'm not logging documentation errors. If there's anything there that's
not a documentation error, then I believe it's unconfirmed.

BTW, I've read that the "good" camera will function only with
"#version 3.5" set. Is that true ?

Fabien.

It's supposed to be.  Guess I should implement that part. :)

  If the default value of 'version' is '3.5', then you don't have to
explicitly write that.
  It just means that if you write "#version 3.1" or smaller it won't work.
