Andrius,

I couldn't find a wiki page on conversion but there's some explanation in 
https://developer.gnome.org/gtk3/stable/GtkIconTheme.html. Stock items became deprecated in 3.10. They're 
still there but the headers moved to gtk/deprecated. You should be able to make it work until gtk-4.0.

If you decide to modernize you need to redo everything theme-able to the new system. Yes, until you do gtk-3 
css themes won't work well, whether adwaita or community-provided.

gtk-app-devel or irc #gtk are better places to get help either with converting or with keeping the old stuff 
working.

I found 3.16 to be unstable on Gramps, too, so I've been using 3.14. That's why it's in the moduleset. 
Christoph set up the HiDPI patch on that too so you can try it. I haven't filed bugs against gtk+ because I 
wasn't sure I could separate out the gtk issues from potential python garbage collection trouble. Since 
Bluefish is C maybe you can generate some good bug reports on the crashes. File them against gtk+, Backend: 
Quartz (after searching for duplicates, of course).
