  Unless your leafMesh is rather large, I don't think there is a significant
amount of memory saving if you make instances of it, each one having an
internal transformation matrix, compared to duplicating those triangles
inside a mesh object. An object instantiation (which consists of a relatively
large amount of data, including a transformation matrix) requires a fair
amount of memory. Although I must admit I don't know how many triangles a
mesh must have before it becomes more memory consuming.
