Tk::Zinc is nicely integrated into Tk, that's good. But I recall that when I tried Tk::Zinc in the past, I wasn't all that convinced. Things have not improved since then.

As of today, it doesn't install cleanly on my current machine (Debian Bullseye) from CPAN. I can force-install (i.e. skip tests), but then the zinc-demos application dies for all OpenGL related demos. The current CPAN testers report doesn't look promising as well. The URL http://www.tkzinc.org/ mentioned in the manual has been grabbed by someone else. So, apparently it is a somewhat ... dry area.

I see that Tk::Zinc tries to make use of OpenGL: It calls OpenGL functions in its own C sources. However, there's no indication in the documentation nor in the demo sources that it offers using OpenGL interfaces through Perl.

So, unfortunately, the Tk::Zinc canvas is not what I want.
