[ann] org-font-spec-preview (preview fonts and test open type features)

[Juan Manuel Macías]

Hi,

I've polished some raw ideas that I shared here a few days ago, and I
have written this little package:

https://gitlab.com/maciaschain/org-font-spec-preview

org-font-spec-preview allows you to preview arbitrary text strings in a
chosen font (or generate a complete specimen) as well as test opentype
features in real time. The preview is done in a temporary buffer, by
executing org-latex-preview, and must be compiled with LuaTeX, since
LuaTeX allows to load fonts that are not installed in the system.

Two user commands are provided:

- ofsp-system-font: Run ido and choose the candidate font from a list of
  fonts installed on the system;

- ofsp-dired-font: Preview a font file in Dired.

Feedback welcome!

Best regards,

Juan Manuel
