+/* Renders a single output_item to an output device in one of two ways:
+
+   - 'print == true': Broken across multiple pages if necessary.
+
+   - 'print == false': In a single region that the user may scroll around if
+     needed.
+
+   Normally 'output_item' corresponds to a single rendering.  There is a
+   special case when 'print == true' and 'output_item' is a table_item with
+   multiple layers and 'item->pt->table_look->print_all_layers == true'.  In
+   that case, each layer is rendered separately from the FSM's internal point
+   of view; from the client's point of view, it is all one operation.
