/* Toolbar control has two ways of reacting to a change. We call them a

* and top margin (the latter in comctl32 <v6), while a relayout uses the cached
* values. This functions creates a flat toolbar with a top margin of a non-flat
* toolbar. We will notice a recalc, as it will recompte the top margin and
