// The general idea here is that if the user clicks directly on a small item inside a larger

// within a footprint, but we also apply it for text within a footprint, footprints within
// larger footprints, and vias within either larger pads or longer tracks.
//
// These "guesses" presume there is area within the larger item to click in to select it. If
// an item is mostly covered by smaller items within it, then the guesses are inappropriate as
// there might not be any area left to click to select the larger item. In this case we must
// leave the items in the collector and bring up a Selection Clarification menu.
