New feature clarification: Animation/transformation

This is probably a question for lummox:

Older object pixel transformation features (pixel_x and pixel_y) seem to increase view-distance buffering once they pass a certain threshold. Is this also the case for animation and transformation translation?

(I'm hoping it isn't.)

They would have to, or they wouldn't be visible if their tile was significantly off screen, wouldn't they?

I wonder how aggressive this is, then, because I'm using transform for a parallax background. Albeit it's in the client's screen, so I don't think it should affect it.

screen_obj
    parent_type = /atom/movable
    starbackground
        icon = 'starbackground.png'
        screen_loc = "1,1"
        layer = 0
        var
            offset = 0
            moving = TRUE
            screen_obj/second
        proc
            parallax()
                var/matrix/M1 = transform
                var/matrix/M2 = second.transform
                while(moving)
                    sleep(world.tick_lag)
                    if(offset==239)
                        M1.Translate(0,240)
                        M2.Translate(0,240)
                        offset = 0
                    else
                        offset++
                        M1.Translate(0,-1)
                        M2.Translate(0,-1)
                    transform = M1
                    second.transform = M2
        New(var/client/c)
            ..()
            second = new/screen_obj()
            second.icon = src.icon
            second.screen_loc = src.screen_loc
            second.layer = src.layer
            second.transform = matrix(1,0,0,0,1,240)
            c.screen += src
            c.screen += second
            spawn()
                src.parallax()

I would imagine that client.screen doesn't do any culling, and so your code won't really affect it. Maybe Lummox JR can confirm that.
