Cache temporary arrays outside of function scope in getCursorPosition

[Srile]

In renderer.ts::getCursorPosition there are currently two arrays that are used to store the inverse Position of the supplied cursor and the object's scale, these cause unnecessary memory allocations at runtime. Can the array declarations be moved to outside of the function scope?

getCursorPosition(c: Cursor): [number, number] {
    const pos = [0, 0, 0];
    const scale = [0, 0, 0];
    this.object.transformPointInverseWorld(pos, c.cursorPos);
    this.object.getScalingWorld(scale);
    return [pos[0] / this.scaling[0] / scale[0], -pos[1] / this.scaling[1] / scale[1]];
}

Thanks!
