You actually do see it, because there will be less risk of colour
banding.

Perhaps, but this is not an essay writing contest. Critiquing the form
of the argument is not entering into the spirit of rational debate as
you appeared to imply you would at the start of your reply. With that
paragraph of yours above, you now appear to be looking for excuses to
dismiss the argument instead of considering it.

This is perfectly true, but how applicable is it to the POV-Ray
community in general. I've no idea.

Still lazy. There's no excuse for it. People thinking that software
will save them effort is a big mistake. I work in the software
industry and know all too well that one form of toil has merely been
transformed into another. If one is not prepared to make an effort,
one does not get the result.

Just because one view of the newsgroup is badly affected does not mean
one has to throw in the towel. Again, effort has its own rewards.
