feat: drawSprite on another layer

[Minamotion]

Is your feature request related to a problem? Please describe.

Let's say I want to draw a background, which is a static image that will never move.
Let's also say that I have this in my code:

setLayers(["bg", "obj", "ui"], "obj")

I want to be able to do this:

onDraw(() => {
    drawSprite({
        sprite: "funnyBg",
        fixed: true,
        layer: "bg"
    })
})

Any more information?

There are some alternatives like:

1. This one

   add([layer("bg")]).onDraw(()=>{
       drawSprite({
           sprite: "funnyBg",
           fixed: true
       })
   })

2. or this one

   add([layer("bg"),fixed(),sprite("funnyBg")])

but I don't think either of those are the best way to do it...

Those are the best ways to do it. Objects are sorted, not draw methods. Objects are sorted by layer, then z.
