In Org mode, in order to create latex previews, we
(1) run latex to generate the preview image
(2) that image is stored in some directory
(3) we display that image over the corresponding latex fragment in an
overlay
(4) we retain the image on disk, so that we do not need to run latex
many times if the users toggles displaying the previews (this is
very important, because running latex is costly)
Can we instead store them in memory? Yes, but (1) it will make Emacs RAM
consumption grow constantly and more and more previews are generated;
(2) it will require significant changes in the Org mode codebase.
