What techniques exist to render rotated text in emacs? By this I mean physical rotation of text by an arbitrary angle and shown inline in a buffer as shown here:
(alignment of text in my sample is not significant)
Inserting an SVG image containing the rotated text comes to mind, but that is subject to emacs being built with SVG and naturally it wouldn't enable text selection. Maybe it could still accommodate search if shown as an overlay.
I'm open to any suggestions. Even limited solutions are highly relevant. For example: if emacs could rotate individual glyphs/characters, but only rotated by 90 degrees or mirrored that would still be plenty useful!
