Rendered, or rendered well?

Parentheses are tall enough to enclose the expression, without leaving too much
horizontal whitespace.

I looked at the first 10 or so images that you linked to.  They don't exercise
this case, really.

But I'm not sure why it matters whether _all_ existing MathML packages do a good
job of rendering.  The point is that they have the option of doing a good job.

That might give you a decent approximation, if your box sizes happen to be just
right...

People believe a lot of silly things.  Especially if you talk about "broadly" as
opposed to "by the people who know what they're talking about."

Do you have a reference on this?  Because I don't recall this being mentioned
anywhere.
