New issue 76 by address@hidden: z-pos confusion and incorrect ordering  
in the editor
http://code.google.com/p/pingus/issues/detail?id=76

Currently Pingus has two ways to order objects:

* implicitly by their position in the object list
* explicitly by their z-pos

This is mostly for historical reasons and has a few issues such as:

* the editor allows to place hotspot and other objects between two  
groundpieces, the game engine does not
* groundpieces have a z-pos, which however isn't very useful as it  
duplicates implicit ordering
* some objects have multiple z-pos, but the editor doesn't allow to  
manipulate them (i.e. prefabs)
* some objects, such as exits, draw to the groundmap as well has have a  
sprite and they need to do that from two different positions, see also
