Hi John,
had some quick check for gtk+3.18.9 +glib-2.45.8 +HiDPI patches together with bluefish.
Indeed, pixelation is gone for all widgets, except gucharmap plugin (when right-click on some letter). It 
is minor issue, but still not 100% fixed. Image sizes are correct.
Toolbar and all other icons are missing. Is there somewhere some guidelines how to get them back? Quick 
googling did not lead to any results. On 3.6.4 we just used stock icons, how to get them back on 3.18?
I am also getting frequent segfaults when closing transient top level windows, and frequent segfaults when 
doing dnd. I am on MacOSX 10.9.5. Backtraces looks like this, so I guess it is gtk+ issue:

Should I fill a bug reports on bugzilla?

Most time-consuming, if I decide to use 3.18, will be theme change. Adwaita probably looks good on tablets 
or  cell photes, however, it is radical change from older PC look. I would need to spend significant time 
amount adapting it to bluefish needs. Community provided gtk+3 themes does not work well on 3.18, for 
example, scroll animation is missing.
Theme development... not really what I want to be involved in.


I couldn't find a wiki page on conversion but there's some explanation in 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 

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).
