and that's without-toolkit-scroll-bars.  So I was mistaken about this
using the Lucid code.  Incidentally, the scroll bar width of the
minibuffer appears unaffected from my settings, and this might be a
bug.  My screen might look a bit prettier otherwise.

So now I don't think it is an option to compile with GTK+ overall while
using Lucid scrollbars.  Sorry for the confusion.

I'm fine with the resulting ugliness in the Emacs-native scrollbars:
using Gtk+ for the rest certainly gives a much nicer appearance overall
than using either Athena Widgets or Lucid for everything.
