Since I've received no other feedback about altering or replacing texvc
before installing it (and I finally have free time!) I will install it
today.

I have listed a couple of minor problems and showstoppers on
http://test.wikipedia.org/wiki/Tex_requests

I still think that it is inane to plan a whole plethora of backend
plugins for various types of graphics, rather than simply support tex
and be done with it, once and for all. The only argument that I have
seen with any weight was that TeX is a programming language and
therefore insecure; the counterargument is that TeX can be run safely
without being able to read or write files it is not supposed to, and
that its memory can be limited to eliminate DoS attacks. Planetmath and
xxx.lanl.gov do just that.

I have given it my best shot, and if you don't agree, I can't do
anything more than that.

It turns out that the one feature I need when editing math, namely
commutative diagrams as on http://www.wikipedia.org/wiki/Snake_lemma ,
I will not get. I guess I have to wait until someone implements an
xypic plugin.

None of them is a "showstopper", and most important of things you
list there: \left and \right - works since the very first version
of texvc.

Brion: Please don't listen to Alex and install texvc.

Any reason these things cannot be fixed later, after it's installed?

Can TeX draw arbitrarily specified maps of the world? Can TeX render SVG
to PNG for browsers that don't support it natively?

"Will not get" meaning that it still needs to be added to texvc, or
meaning that there is some fundamental incompatibility between texvc and
commutative diagrams?

You can read my reply on http://test.wikipedia.org/wiki/Tex_requests
In one sentence: no such reason

TeX can do none of these.

It's rather "it still needs to be added to texvc".
No real incompatibility here.

I apologize, I must have missed it in the documentation :-) This
feature can actually also be used to produce the case distinctions I
complained about:
<math>f(x)=\left\{\begin{matrix}n/2&\mbox{if }n\mbox{ is
even}\\3n+1&\mbox{if }n\mbox{ is odd}\ \end{matrix}\right.</math>

Note that something goes wrong if one forgets the \right command.

I don't know if texvc is flexible enough to handle the rather bizarre
syntax of xypic. If not, a separate plugin would have to be written.
