After looking more at the code, I figured that alignment of 3D models
and sprites was already pretty much built in :-). All it took was
changing the origin of the cube-shapes from 0,0,0 to whatever offset
fitted best. A little extra code was required to get it working, but
the result looks good to me (see attachment).

With the synchronization out of the way, I can continue with other
remaining issues. For that, I made some more improvements to the
collision debugging code (also shown on the image below). This doesn't
completely eliminate the need to use gdb to track down issues, but it
helps a lot :-).

Get the code from CVS and have a look yourself, if you want. Help is
also welcome, of course, but I can understand that it is quite hard to
get into the current code without much documentation around it.
Something I should change soon ... at least I would like to get some
sketches up on the wiki that demonstrate the placement of objects on
the map and the alignment between the images and underlying models.
