Oh! You mean that basically I have to build everything in GIMP? Oh dear.
That will mean that all the image material will end up being on a single
layer in Scribus, which will make the layout much more difficult than I was
expecting, since I will have to lay out all the image material precisely in
GIMP, which is much harder than doing it in Scribus.
I thought I was trying to do something easy, but apparently not :-(
