OK, but I'm still not seeing how switching Debian's wxwidgets3.0 package
to use GTK3 is really relevant to that goal.

Moving our wx packages to GTK3 is something that's clearly going to need
doing at some point, and if we don't do it for buster then boinc-manager
will need patching not to use wxWebView (because the GTK2 implementation
is build on an obsolete webkit version).

But I'm not following why GTK3 is desirable for pgadmin3.  At some point
I may need to make a call as to which way we go, so I'd like to
understand why switching to GTK3 is good or bad for particular rdeps

I'm not really sure what's most likely at this point.  The least effort
solution is almost certainly sticking to wx3.0 + GTK2 and patching
boinc-manager to use wxHtmlWindow, but that's not entirely satisfactory.

BTW, the GTK3 issues I've found so far all affect both and git
master, so the 3.0 vs 3.2 decision looks like it may be fairly
orthogonal to the GTK2 vs GTK3 one.
