Subject: [RFC PATCH] docs-rst: move the rules for svg and graphviz to Makefile.sphinx

Not only media documents may have images. So, move the
rules for building images from graphviz and from SVG to
the Documentation makefile.

With this change, if some Documentation subdir "foo"
can now specify that he has SVG and/or DOT source images
that are included inside the documentation.

All it is needed is to create a Documentation/foo/Makefile with:

DOTS += foo/bar.dot
IMAGES += foo/foobar.svg

and, at Makefile.sphinx, add a:

include foo/Makefile

The build system will generate the SVG image "bar.svg" from
the graphviz "bar.dot" document for all documentation targets.

If the documentation target is latexdocs or pdfdocs, it will
also produce a "bar.pdf" image from "bar.svg", and a "foobar.pdf"
from a SVG source image called "foobar.svg".

NOTE:
====

This is a RFC patch, based on this patch series:
https://lkml.org/lkml/2016/11/20/89

If you think it is worth, I'll write a documentation patch for the doc-guide/
providing a complete guide about how to add an image at the Kernel's
documentation.

Is there a branch somewhere with all this? I'd like to play around with
pulling graphs into the gpu docs ...

Sure. Just pushed it to:
https://git.linuxtv.org/mchehab/experimental.git/log/?h=svg-images

You can pull it from:
git://linuxtv.org/mchehab/experimental.git svg-images

I also just added a patch documenting it:
https://git.linuxtv.org/mchehab/experimental.git/commit/?h=svg-images&id=ca3b1faaae9dcfcbf0f4a119bf5eb3df0cb6c001
