/* Deciding if we should show a separator is a bit difficult. There
* are two types of separators:
*
* - section headings (when sections have 'label' property)
*
* - normal separators automatically put between sections
*
* The easiest way to think about it is that a section usually has a
* separator (or heading) immediately before it.
*
* There are three exceptions to this general rule:
*
* - empty sections don't get separators or headings
*
* - sections only get separators and headings at the toplevel of a
* menu (ie: no separators on nested sections or in menubars)
*
* - the first section in the menu doesn't get a normal separator,
* but it can get a header (if it's not empty)
*
* Unfortunately, we cannot simply check the size of the section in
* order to determine if we should place a header: the section may
* contain other sections that are themselves empty. Instead, we need
* to append the section, and check if we ended up with any actual
* content. If we did, then we need to insert before that content.
* We use 'our_position' to keep track of this.
