Pre-review questions about image(s) and translations

[Urs Liska]

Hi,

I'm going to continue my website work.
As discussed earlier I have written an additional page about the 
editing->compiling concept. While this is essentially self-evident it 
seems that we need an additional step to get new users on the right 
track here. The page will be added between "Text input" and the "Easier 
editing" page with the editors' list.

Before uploading a patch for review I have a set of technical questions 
regarding images.

You can see a draft of the new page at 
http://www.ursliska.de/lilyweb/editing.html (any clickable items won't 
work there).
Although I will of course listen to comments about the content I would 
appreciate if the discussion could mostly concentrate on the technical 
issues.

As you can see I have created a flowchart to visualize the relation 
between the different parts of the editing cycle.

If it were simple the two PNG files I knew that I would have to add them 
to lilypond-extra and open a pull request so Graham could add it there.
But: This image is generated with LaTeX and contains text that should be 
localized.

So:
a) in what form should I provide such an image that it can be
translated and modified in the future? I.e. I would prefer to add the 
.tex source somewhere and have some automated way to process it 
(including the conversion to PNG which I've done manually for now).
b) is there a way to provide a way to generate vector versions for use 
in the PDF manuals?
