WIP : Outline not working locally

[hustf]

This is not working locally. It's probably a good idea to try this out on another operating system than mine.

Three unresolved reasons for taking a break locally right now. I still think this is a good idea, though:

1. It is unclear to me whether [deps] sholud include the projects from [weakdeps] when we do not require Julia < 1.9.
   I tried to remove the [deps] entry for LaTextStrings and Mathexengine (previous PR). But that did not seem to work.

2. FFMPEG won't fully install on my computer. Possible reason explained in FFMPEG issue. If Luxor is CI tested on Windows, we would probably need to modify the script. And the important point is that Luxor starts working better on Windows computers without those special codecs.

3. I'm struggling with this Julia issue, too, which I'm meeting. I believe it has to do with the package registry and showing differences.

Label this WIP for now?

[hustf]

Yes, but not sure I can label things even when I'm on a computer.

Note for when I / we pick this up: Julia issue 3327 fixed in 3591 and the fix was included from Julia 1.9.4.

[stale]

Is this still relevant? If so, what is blocking it? Is there anything you can do to help move it forward?

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs.
