/******
 
Simple llDetectedGrab illustration, rez a prim and add this script.
The prim will become a cone that follows mouse grabs.
 
 Click and hold the mouse button down on the object, then:
 - Drag left and right to move parallel to the camera focal plane.
 - Drag up and down to move to and from the camera.
 - Hold down Ctrl, then drag up and down to move vertically.
