I don't think that's generally possible to fix "well" without a totally 
different shadow model (i.e. actually draw shadows in libkmahjongg 
instead of having them faked in the tileset graphics).

Although... since the shadows are soft-edged in mine, I think it's less 
noticeable (there is still the "dimple" between two tiles, though).

Right. This is something I've thought of from when I was writing an 
OpenGL-based 3d mahjongg.

(If we do anything like that, PLEASE do it so it will work with 3d tiles 
also!)
