[3dprinter-general] Bug#1114498 and #1114499

[Gregor Riepl]

Hi,

>     + #1064598: yagv: crashes with "module 'pyglet.graphics' has no attribute 'vertex_list'"
>     + #1050157: printrun: broken 3D view due to pyglet 2+

Both of these packages depend deprecated OpenGL 1.x interfaces in Pyglet <2.

Unless they get ported to Pyglet 2 (and OpenGL 2+), it will no longer be possible to support them.

Related upstream discussions:

https://github.com/kliment/Printrun/issues/1468

That being said, it may be possible to keep printrun alive by just removing the parts that require pyglet. printcore.py and pronterface.py should work fine without it.
