Implemented solution for #2110 (small cells and ghost cells) 

The solution consists of a second path to bounding boxes of
cells - namely "bbox_with_empty". This bounding box is a
(0,0;0,0)-box if the cell is empty. Correspondingly, empty
and ghost cells are displayed as single points. Ghost cells
also behave like hidden cells now.
