This is now mostly working, but not efficient.

This branch will need at least GTK 3.20 now.

Switching off animations in gtk-3 makes this branch perform much more like the gtk-2 version, on Cosma at least.

This is still likely to be a bit slower because the images are generated by the Fortran code are in a different format from the 32 bit ARGB needed by Cairo, so there's a conversion to do on every frame. To eliminate that I'd have to get a pointer to the Cairo surface data, have the image generation code update the surface directly, then mark the surface as updated.
