// check if there is an SVG <path> behind the selected <g> object
// if true
// select the <path> element behind it
// calculate a center coordinate
// for complex shapes, best solution may be to add up all the x, all the y, and divide each by
// respective count of x, count of y
// for current item that was being dragged, set its new x + y position to the new calculated center
// point of the <path> behind
