Re: Why does a `standalone` document set `TeX-PDF-from-DVI`?

For me, the simple test file actually calls the following hook (in
style/tikz.el):

(TeX-add-style-hook
 "tikz"
 (lambda ()
   (TeX-add-symbols
    '("draw" (TeX-TikZ-draw-arg))
    '("coordinate" (TeX-TikZ-coordinate-arg))
    '("node" (TeX-TikZ-node-arg)))
   (LaTeX-add-environments
    '("tikzpicture"))))

Thus, I already get completion for tikzpicture. As I wrote before, the
hook was called when processing the `tikz` class option of the
declaration `\documentclass[tikz,border=5pt]{standalone}` (I found this
out using the elisp debugger).

I am a bit surprised that there is no function for this already.

Otherwise, I think the code looks good. I am not familiar with all the
options, and honestly I've never used the standalone *package* (only the
document class to create a PDF).
