[PATCH] Babel: remove LaTeX environment -type #+results

Hi All,

I think there's potential for some really nice experiences leveraging
Org's latex rendering in combination with some languages' symbolic maths
ability.

This is /very nearly/ already supported, `org-babel-result-end' just
needs to be tweaked to also remove LaTeX environment -type #+results.

This is what I'd like to make possible:

Subject: [PATCH] ob-core: Remove LaTeX environment #+results type

* lisp/ob-core.el (org-babel-result-end): By adding latex-enviroment to
the possible results types, a much richer experience is possible for
backends that can produce LaTeX-formatted maths as their results (for
example: Calc, Julia with Latexify, Python with SymPy, Octave with
symbolic). This is superior to a LaTeX export block as LaTeX
environments can be (1) rendered inline, and (2) better used in
non-LaTeX export formats (e.g. HTML with MathJax).  Without this,
backends can output a LaTeX environment, but new results will be added
in front instead of replacing the environment.

Timothy,

interesting.  would this show up in #+RESULTS blocks?  in (heaven
forbid!) #+BEGIN_SRC blocks?

cheers, Greg

The screenshot where it shows up is from the following Org buffer
(manually constructed for the example):

#+begin_src julia
[1 2; 3 4]
#+end_src

#+RESULTS:
\begin{equation}
\left[
\begin{array}{cc}
1 & 2 \\
3 & 4 \\
\end{array}
\right]
\end{equation}

#+begin_src julia
using Symbolics
@variables t
2^sin(t) + cos(t)/t
#+end_src

#+RESULTS:
\begin{equation}
\frac{\cos\left( t \right)}{t} + 2^{\sin\left( t \right)}
\end{equation}

The rendering is just done by `org-latex-preview'.

Hope that clears things up.

Applied in master as commit b90b850ae.

Can you add a etc/ORG-NEWS entry for this?
