callbacks: prepare to support gtk 4 render
The cairo way to draw pixmaps got removed on Gtk 3.94:
https://gitlab.gnome.org/GNOME/gtk/commit/7ef8696a7dc2c7ad5965f7150acb51b1c0559a84
We'll likely need a different solution for it to work. So,
for now, just print an error if someone tries to print with
gtk versions above 3.90.
