[Debian-med-packaging] Bug#1122272: gwyddion: Cannot render 3D image as the gwyddion was not built with OpenGL support.

[Étienne Mollier]

hi harvey,

Thank you for your report, the build configuration does include
--with-gl, but GL support does not make it to the resulting
build due to GtkGlExt support missing in the build environment,
per configuration summary[1]:

	[…]
	=================================================================
	Configuration Summary:
	  OpenGL 3D widgets:               no (needs GtkGLExt)
	[…]

I'm afraid enabling OpenGL support is going to require bringing
back libgtkglext1-dev, which dropped from Debian somewhen
between bookworm and trixie.  I see what I can do for unstable.
Maybe something is achievable by moving to gwyddion 3, thanks to
the bump to gtk3 upstream; that would also resolve #967514 about
upcoming drop of gtk2 from Debian, bug which has become release
critical recently.  Upstream still dubs gwyddion 3 as unstable
though.

Let's see how far I can get…
