Returns the screen position of the viewport as an IgePoint3d where x is the "left" and y is the "top", useful for positioning HTML elements at the screen location of an IGE entity. The returned values indicate the center of the viewport on the screen.

This method assumes that the top-left of the main canvas element is at 0, 0. If not you can adjust the values yourself to allow for offset.

var screenPos = entity.screenPosition();
