Shapes can be centered about the X, Y or Z axis.

Note: The center of a shape is calculated as the midpoint between minimal and maximum points.

let myshape = sphere({radius: 5})
let newshape = center({}, myshape)  // center the shape across all axes
newshape = center({axes: [true, true, false]}, myshape)  // center the object across only X and Y axis
newshape = center({center: [5, 6, 7]}, myshape)  // center the shape at the given center
