#72 Resurrect background image support

[Egmont Koblinger]

RoxTerm used to support background image.

Even though libvte-2.91 (vte tarball >= 0.38) no longer explicitly supports background image, it is possible to work it around with a bit of Gtk+ magic, by drawing behind a transparent (or translucent) vte widget.

See the Terminix project which has already implemented this.

(Seems to me that feature requests are not yet migrated to github?)

So, both Tilix (formerly Terminix) and xfce4-terminal have implemented background image support using some GTK+ magic.

Moreover, vte-0.52 introduces a new API vte_terminal_set_clear_background() which is intended to somehow make it easier.

Don't ask about the details, I'm not familiar with them, sorry.
