    gtk-demo: Replace old code
    
    "Hey I know, let's do an easter egg!"
    "What kind of easter egg?"
    "We can nest lots of textviews!"
    "Sounds cool!"
    ...
    "But how does one see a textview inside a textview?"
    "What do you mean?"
    "Well, it just looks like black text on a white background."
    "You mean it's the same as if we just duplicated the text?"
    "Yeah!"
    "Hrm, maybe we can put a frame around it."
    "Sounds good. I'll stuff the textviews in a GtkFrame."
    "What? Why? Let's use a GtkEventBox and override its background"
    "Why is that a good idea when we have GtkFrame?"
    "Because I said so!"
    "Okay."
