[Fluxus] texture transparency for particles

So this would become a issue when we'd have something like Tetris shapes
fitted together and looked at from a odd angle? In that case we'd have to
treat all parts of the object as separate objects and potentially chop faces
into bits like I did to my plane?

Plane pasted below for illustration.

(with-state
(colour (vector 0 0.8 0))
(for* ((x (in-range -5 5))
        (y (in-range -5 5)))
    (identity)
    (scale 5)
    (translate (vector x  y 0))

    (build-plane)))
