the base game recently added a nice looking shader for the leaves of trees.
So in the modding world there happen to be trees in the sprites/animations of other entities, which now stand out because their leaves don't move (or not in the same way in case one added an animation).
So I wanted to suggest adding a 'draw_as_leaves' property to sprite/animation definitions, similar to the 'draw_as_shadow' property, which applies the shader regardless of the prototype type.
(This might also make the tree prototype definitions less arcane
)
