I'd like the Linux version of Solvespace moved from GTK3 to GTK4. I did some preliminary build changes on the GTK4 branch and opened an issue on github here: https://github.com/solvespace/solvespace/issues/1414

This is rather far outside my wheelhouse, so I'm looking for someone to handle this task. Prefer someone who might stick around as a developer, but a drive-by migration would also be fine with me.

GTK4 should be optional on Linux for now, but it will become default in the future. I also see GTK4 eventually used on all platforms, so we can clean up the text window (think scalable text and accessibility) among other things without having to do it separately on all three platforms. That is years away though, and there is plenty of improvement to be make without invasive GUI changes.
