Excellent!  :)

Sorry for not having replied a bit sooner, I was still trying to
make sense of the situation.  I confirm the OpenGL library is
made available in my Stretch boxe in version 1.2.0:

	$ dpkg -S /usr/lib/i386-linux-gnu/libGL.so.1.2.0
	libgl1-mesa-glx:i386: /usr/lib/i386-linux-gnu/libGL.so.1.2.0

Also, if I may add, you wrote:

True, it is not needed.  I guess it may even be unwelcome on CNC.
