Yes I started on updating the 3D code to modern OpenGL which would work with 
GTK3 but that is a way off - I’ve been fully occupied because of covid since 
March so not sure when I’ll get back to it.

For me the GTK3 experience on Windows isn’t great. Slow gui, crashes and 
glitches. That may be caused by the version of GTK I had installed though.
