Well Speaking of all tiles using grass as a base. Shouldn't we replace all of 
them with 2 tiles, one having a alpha layer? I want you to take into account 
this, speaking back of smoothing:
If i have a tree ontop of grass, should it smooth as grass or as a tree?
If it smooth as grass, mountains should overlap over it. This means we will 
get the feeling that the moutains grows on top of tree (quite unnatural, 
you'll agree).
If it is smoothed like a tree, what graphics will see in the border? Small 
young trees without grass? The grass at the bottom will end abruptly and we 
will lose the advantages of smoothing. So we would put, perhaps, small young 
trees and a bit of grass below. But all those would be drawn at level of tree 
and so the grass associated will overlap the mountains, which is in 
contradiction with the fact mountains should go over grass. And the result 
will also be ugly (abruptly ended mountain and grass over the mountain).
The only solution i see is transforming on map a tree with grass as 2 objects, 
grass and a tree on top (same with forest over grass, forest over hills, 
aso.)
This problem is not new. The weather code, as i can remember, has this problem 
when you need to put snow above the grass but below the trees. The code than 
replace, on the fly, this object by a pair of object (grass and tree) and 
then put the snow. I understand we comes to a problem as client only knows 3 
layers of a square map. If you put grass+snow+tree+player on a square, one of 
them must disappear. But this is already the case due to on the fly 
manipulations of weather code, and i think we should consider replace those 
object in maps (a script could be created which does the work.) A solution 
concerning snow could be to create a 'snowed grass' object, but am not sure 
this is needed.

What do you think about it? This could save a lot of time for drawers when 
dealing with smoothing or other, future maybe, updates of graphics.
