Actually .... There's a step needed prior to this one.  If you have
multiple raster layers, Thuban should draw them on top of each other.
Currently, if I load a map which is 1000 x 1000 pixels, and and
another map which is 200 x 200 pixels and overlaps the first, Thuban
only displays one of them.

There only seems to be code for drawing one background bitmap.
