Hi smart folks!
In aaccbb2f9, I fixed the clipping problems plaguing Babel LaTeX/SVG
output by adjusting Inkscape arguments. Here, I fix the same problem
but for Org LaTeX fragments, this time adjusting dvisvgm arguments.
Also, I also made before/after screenshots, so that you can readily see
the difference. Thank you for your time!
Rudy

Subject: [PATCH] org.el: Compute exact bounds when converting LaTeX output to
SVG
* lisp/org.el (org-preview-latex-process-alist): Call `dvisvgm' with
`-e' (`--exact-bbox') instead of `-b min' (`--bbox=min') to measure
the exact bounds around visual glyphs, as opposed to using font
metrics, to avoid clipping at the edges.

Maybe you can use full argument versions instead of short ones?

Good idea, Ihor! Please see the two attached patches. I re-attach the
first patch again because I reworded the first line of its commit
message to put more emphasis on the term "exact".
