Wayland: Failed to initialize xkb context

[Olivier ARCHER]

When running examples on ubuntu 23.04 with wayland:

#!/bin/env python
from animated_drawings import render
render.start('./examples/config/mvc/different_bvh_skeleton_example.yaml')

xkbcommon: ERROR: failed to add default include path /home/oarcher/anaconda3/envs/animated_drawings/share/X11/xkb

The workaround is to set XDG_SESSION_TYPE env var to x11 before running the example:

export XDG_SESSION_TYPE=x11
