org-preview-latex-fragment and preview-copy-region-as-mml

Hello

I am starting to use org-preview-latex-fragment also in non
org buffers, including message buffers.

What would be extremely helpful is to actually send the
images generates in the message buffers as images.

Preview-latex provides such a functionality
preview-copy-region-as-mml, from  a LaTeX buffer.

Of course the 2 preview functions org-preview and the
latex-preview function work differently. I had a look 
preview-copy-region-as-mml  and it is not clear to me how to
make if work for png generated by org-preview-latex-fragment
in a message buffer. 

Maybe some of the maintainers of org mode or auctex are
interested in having a look?

(ccing gnus mailing list, in case someone is interested)

I ran into that the other day.

I think it would be very useful to have preview-buffer work
on non-latex buffers.

a kludge (was: org-preview-latex-fragment and preview-copy-region-as-mml)

Concerning org-preview-latex-fragment: I have some code
which indeed attaches the png generated by this
function. However it is very primitive. 

org-preview-latex-fragment generates pngs in a subdirectory
called ltxpng. These pngs are then inserted  in
the buffer where org-preview-latex-fragment was executed. Since
one cannot be sure that the ltxpng  directory is non-empty, IMHO it
should be deleted before generating the png.

This is done by function 
my-delete-ltxpngdir, which needs the trashcan pkg.

Then a very simple modification of an already existing
function does the rest:
message-attach-all-png-from-ltxpngfolder.

I attach it if you want to test it.
