FWIW,I've been trying to port the PGTK version of Emacs to GTK 4 (which
will eventually replace GTK 3) without relying on any obsolete APIs such
as Cairo, and so far it hasn't worked very well.  I thought it would
have been finished by December, but the GTK 4 drawing model leaves too
much to be desired.

Not to mention that I had to reinvent file dialogs, menu bars, and popup
menus, since there are no reasonably designed versions of those in GTK 4
which don't involve a single static XML file.

So sticking to GTK is not a good choice, and certainly not a long-term
option.
