    tdf#88276: Add background colour toolbar and sidebar buttons

    but they do nothing yet, follow-up commit(s) add real functionality
    to them

I take it that bNeedTextSpacing = true where it used to be mpToolBoxSpacing->Enable()
so fall-through that happens anyway also sets bNeedTextSpacing so presumably
everything is ok here
