Re: [Gwyddion-devel] Dropped support for gtkglext in debian

In principle it could be included, but there is a strong push against 
including unmaintained software. It would sure works for now, but become 
a nightmare when GTK2 is removed from future versions...

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1054392

I wonder if calling directly on X11 and GL calls would imply in terms of 
the codebase, and how stable these calls are going forward...

Thanks,
Nicola
