So yes, seems that gtk_image_get_pixbuf is available only for old GTK3. I don't 
know what does replace it for GTK4, and I can currently NOT write a working 
GTK4 example for you. Another one just asked for a libadwaita example 
(<https://github.com/StefanSalewski/gintro/issues/120)>, so maybe I should do 
that first?
