I don't know about that.  The tileset knows what sprites are available, 
but ideally it knows nothing about what terrain those sprites represent. 
  But there is already a strong tie between ruleset terrain types and 
their tilespec entries.

In summary, this is a tricky question.

Ugh.  Currently non-iso tilesets do manual blending of all terrain 
types.  This possibility makes things much trickier.  I suppose this has 
to be tilespec-controlled, although that will probably introduce even 
more dependencies between ruleset and tileset.
