rename position_x, position_y, position_z to offsets #499
Description
We should probably rename all the position_<axis> properties to offsets since that's where the WorldObject is placed and does not indicate the buffer data, ex. positions geometry.
realized when doing #498 that this can get confusing
Maybe have:
class Graphic
@offset.setter
def offset(self, offset: tuple[float, float, float]):
x, y, z = offset
self.world_object.world.x = x
...
