One way this _could_ be done is to restrict the GtkScale api to just
add undecorated marks, and then have a special-purpose
"DecoratedScale" container that would have one slot for a scale, and
then allow to add other children to decorate the scale, using child
properties for the position and the value. The container would then
use the
scale marks api to add the marks at the positions/values which its
children request,
and position the child widgets next to the marks.

Not sure the minor benefits justify the effort, though...
