This is http://cgit.freedesktop.org/libreoffice/core/tree/extensions/source/plugin/unx?h=libreoffice-5-1 and thus http://cgit.freedesktop.org/libreoffice/core/tree/extensions/Executable_pluginapp.bin.mk?h=libreoffice-5-1 and http://cgit.freedesktop.org/libreoffice/core/tree/extensions/Library_pl.mk?h=libreoffice-5-1.

The (imho uneeded) "use npapi plugins inside LibreOffice" feature....

Probably depending on gtk2 since "the browsers (read: firefox/icewasel)" do,
which is wrong noadays. But It uses gtk itself:

(sid)rene@frodo ..0.0.beta2/extensions/source/plugin/unx % grep -r gtk_ *
npnapi.cxx:                        pInst->pGtkWindow = gtk_plug_new((GdkNativeWindow)reinterpret_cast<sal_uIntPtr>(pWindow->window));
npnapi.cxx:                        gtk_widget_show( pInst->pGtkWindow );
npnapi.cxx:                        pInst->pGtkWidget = gtk_socket_new();
npnapi.cxx:                        gtk_widget_show( pInst->pGtkWidget );
npnapi.cxx:                        gtk_container_add( GTK_CONTAINER(pInst->pGtkWindow), pInst->pGtkWidget );
npnapi.cxx:                        gtk_widget_show_all( pInst->pGtkWindow );
npnapi.cxx:                        pInst->window.window = reinterpret_cast<void *>(gtk_socket_get_id( GTK_SOCKET(pInst->pGtkWidget ) ));
npnapi.cxx:                    gtk_widget_set_size_request( pInst->pGtkWidget, pWindow->width, pWindow->height );
npnapi.cxx:                    gtk_window_resize( GTK_WINDOW(pInst->pGtkWindow), pWindow->width, pWindow->height );
npnapi.cxx:                    GdkScreen* pGdkScreen = gtk_widget_get_screen( pInst->pGtkWidget );
npwrap.cxx:        gtk_init(&argc, &argv);

No idea about whether the API used changed between gtk2 and gtk3...

And this is the evolution ab thingy. Probably depending on gtk2 because
of evolution (which also changed). I mean, it doesn't use gtk directly afaics:

(sid)rene@frodo ..ta2/connectivity/source/drivers/evoab2 % grep -r gtk_ *
1 (sid)rene@frodo ..ta2/connectivity/source/drivers/evoab2 %

I don't believe they are.
In fact, 5.1 will the first release even enabling gtk3 per default upstream
and the VCLPlug (-gtk3) is the first step. So..

If you wanted to do that, that would be nice.
