Updated the c fixture to be a little more consistent with other fixtures in the corresponding image. for example both e and g both have edges connected with the fixtures that they explicitly depend on.
The PDF documentation on readthedocs was missing the figures in the
fixtures reference chapter. This PR uses a Sphinx plugin that
automatically converts the checked-in SVG files to the PDF input files
that LaTeX requires.
The SVG-to-PDF conversion is done by inkscape, which gave the best
conversion among the tools I tried. However, it [does not yet
understand][href-bug] that you can write a plain `href` instead of
`xlink:href` in svg files, so I’ve had to edit the SVG files
accordingly.

A case with a fixture use both as an autouse and explititly
was raised. This case sounds too narrow to add to documentation
(and could be misleading for people learning pytest with explicitely
using an autouse fixture). At the same time there was no documentation
on the autouse vs regular fixture order, therefore this commit adds
such an information. Code sample grew and it was extracted to the file.
