Situation:
So I'm drawing in the GIMP. I have a layer with only one type of object on it. It is a BIG object, several hundred pixels by several hundred pixels.

I want to do two things:
1. Move it around, perhaps rotate it, until I am happy with its placement with respect to the other layers.
2. Copy it and paste it several times throughout that same layer in different locations.

(I know that it can be copied and used as a brush from them on, but when I try that, only part of the object becomes the brush. I assume that that is because of the object's size.)
