Someone correct me if this is answered elsewhere, but I have a question
anyway...

I've manually bound a union, and set both Remove_Bounds=off and
Split_Unions=off

POV-Ray, on the messages window shows that both these options are correctly
set.

And then, it gives me a message for several (in this case hundreds) of
unions that it has split.  (I have hundreds of these suckers, and I'm
experimenting to see if I can find a better bounding box)

Anyone know if this is supposed to happen?  The manual indicates that manual
bounds are left alone.

Thanks in advance,
...Chambers

I see that, yes.

However, looking into the source code it seems that infinite objects still
cause this message to appear anyway.

So, if I remove the planes and use boxes (the planes being the only infinite
objects I'm dealing with), it will work?  Thanks, I'll give it a try!

OK, now it gives me:
Warning: Degenerate CSG bounding box (not used!).

Anybody know what this means?
