/*
4.3.0 added floating toolbars, but failed to add the ability to restore them.
We need to store there geometry (four ints). We cannot change the format in a
patch release (4.3.1) by adding ToolBarStateMarkerEx2 to signal extra data. So
for now we'll pack it in the two legacy ints we no longer used in Qt4.3.0.
In 4.4, we should add ToolBarStateMarkerEx2 and fix this properly.
