And more than that, I still don't understand at this time how it could
be done in libvstgui either. Perhaps I'll figure it out ...

No, because the GUI is not made of up of tiled-together pixmaps. The
pixmaps are packed together using a packing metaphor derived from TeX,
GTK+ and Qt. There is a huge difference between the way a "background
pixmap" is used in such circumstances to the way a "foreground" pixmap
is used. Background pixmaps will be tiled by the X server to fill
whatever space is required; foreground pixmaps will be left at their
natural size.
You seem want to a system where you just put images all over the
place, tiling them as you go. You could do that, but the GUI could not
animate the knobs or whatever because they could not exist as
"foreground" pixmaps - everything would be in the foreground.
Maybe it would help to add:
<!ELEMENT line (graphics-context?,widget,widget)>
so that you could at least draw lines between widgets ? hmm, probably
not so great.
