Maybe it's just a poor tab setting.

One could subdivide a triangle into three quadrilaterals (add a point in
each edge and one in the middle); but it does seem like going the long
way around the barn, essentially to make up for a defect in the syntax.

I assume the normals of a smooth_triangle are linearly interpolated.
Hm: you have three known zeros (i.e. f(x0,y0,z0) = f(x1,y1,z1) =
f(x2,y2,z2) = 0) and nine partial derivatives, to which you can fit a
polynomial function -- but then you'll have to clip this iso into a
prism or pyramid whose shape may not be so easy to determine.

I do - variable width fonts are easier on the eye.
The only time it matters is when someone includes ascii-art in a post,
and, realistically, just how often does that happen ? On the rare occasion I
do want to see some ascii art in a fixed width font I just copy and paste
into Notepad...

People post code quite often, and indentation suffers quite a lot with
variable-width font, as well as general readability (delimiters are much
harder to distinguish when they are really small).
Smileys are just plain horrible with variable-width fonts.
Also people usually write text so that the length of the lines is
approximately the same, thus getting approximately justified paragraphs,
which are nicer to the eye. With variable-width font you probably get
much more variation in line lengths.

Hmm... I can see your point, but I can't see the problem - I have no
problem with reading code in a variable-width font. Though I could never
write code in a variable-width font...
> Smileys are just plain horrible with variable-width fonts.
Again, I don't see the problem - they look just fine to me...

URGH! I _hate_ that all straight lines down each side - I always want to
mess 'em up a bit...
I guess it's all a matter of taste...

I hate trying to read code in variable-width font...especially when
things are nicely lined up in fixed width font.

He said "approximately", he wasn't talking about having the words
perfectly aligned to both edges, but something like this message. Having
gaps at the edges for no reason would be terrible for readability. Using
a fixed width font makes sure you see what everyone else sees.

That's just it - I don't think it is - I find it more, um, natural -
maybe it's just me...

He said "approximately", he wasn't talking about

You can't be serious...I suspect you are trying to say something
completely different, because I don't see how anyone could think
something so random could be better than naturally flowing text.
Having a straight line down the left side is much easier to read, it
gives the eye a definite location to switch to after the end of a line.
Forcing the right side to be even hurts readability, because it causes
unnatural spacing in the words. Having the text centered is even harder
to read, since the eye has to search for the beginning of the next line.
Having both sides uneven would be the worst possible way, and I don't
see why anyone would bother to do it.

Yes, I am saying something different. I agree, the left side should be
straight, but Warp said "people usually write text so that the length of the
lines is approximately the same, thus getting approximately justified
paragraphs", i.e. the right hand side, though not completely straight, is
roughly straight - it's that that I dislike.
I dislike completely justified (with both left and right sides
completely straight) even more.
I just like text to be a bit more random than "approximately justified".
For example, as I write this, the ends of the lines of my first paragraph
are in a roughly straight line, and I want to put a couple carriage-returns
in to make them less uniform, but won't 'cos I know it'll screw things up
completely when OE comes to wrap them at 76 characters...
Of course, it could be taken to extremes, with hugely varying line
lengths, and that's just as bad, if not worse.
I'm not sure I could define the points at which it's either too random
or too justified, so don't ask...
Anyway, this is all getting way off-topic for p.u.p...
