Thanks! I had found gtk3-nocsd. I initially ran across it many years
ago when trying to get evince to act like a good X11 app, but
switching from evince to atril solved that problem without having to
try gtk3-nocsd.

gtk3-nocsd was a seperate library that replaced a few GTK3
functions. It was used by setting LD_PRELOAD so that the gtk3-nocsd
library was searched first -- that way it could be applied only to
specific executables.

OTOH, gtk3-classic is a set of source patches that get added to the
"normal" gtk portage directory. Those patches are then used the next
time gtk3 is emerged. That means that it's a permanent, system-wide
change: all executables that use GTK3 will be using a library that has
the classic patches.

Am I undertanding the mechanisms correctly?
