Convenience constructor for supporting picking in WINDOW, or PROJECTION coordinates In WINDOW coordinates creates a start value of (x,y,0) and end value of (x,y,1). In PROJECTION coordinates (clip space cube) creates a start value of (x,y,-1) and end value of (x,y,1). In VIEW and MODEL coordinates creates a start value of (x,y,0) and end value of (x,y,1).
