/**
* \brief Arranges the model objects on the screen.
*
* The arrangement considers multiple bins (aka. print beds) for placing all
* the items provided in the model argument. If the items don't fit on one
* print bed, the remaining will be placed onto newly created print beds.
* The first_bin_only parameter, if set to true, disables this behavior and
* makes sure that only one print bed is filled and the remaining items will be
* untouched. When set to false, the items which could not fit onto the
* print bed will be placed next to the print bed so the user should see a
* pile of items on the print bed and some other piles outside the print
* area that can be dragged later onto the print bed as a group.
*
* \param model The model object with the 3D content.
* \param dist The minimum distance which is allowed for any pair of items
* on the print bed in any direction.
* \param bb The bounding box of the print bed. It corresponds to the 'bin'
* for bin packing.
* \param first_bin_only This parameter controls whether to place the
* remaining items which do not fit onto the print area next to the print
* bed or leave them untouched (let the user arrange them by hand or remove
* them).
* \param progressind Progress indicator callback called when an object gets
* packed. The unsigned argument is the number of items remaining to pack.
* \param stopcondition A predicate returning true if abort is needed.
