latex fragments in html export

[Matt Huszagh]

Hello,

Has anyone had success getting the html export to process latex
fragments? It's leaving mine completely alone and I can't figure out
why. Latex babel source blocks work fine. I've set

(setq org-html-with-latex luasvgm)

luasvgm is a process-alist element I defined. I went through ox-html and
set up debug points in a bunch of functions meant to process latex
fragments, but none of them are being called.

Thanks
Matt
