Update 6 May 2018 (sampling downto 45% with color cameras to take account of Bayer matrix)
Update 28 Apr 2018 (add recent cameras; diffraction spot size; color simulation not enabled on server)
Update 3 May 2016 (better rendering of all simulations)
Update 2 Jan 2016 (simulation of sampling, optical resolution, frame resolution)
Update 27 Dec 2015 (simulation of field of view)
Update 21 Nov 2015 (add cams; read-only fields grayed; choose either f/D or focal)
Update 5 Sept 2015 (better accuracy for very short focal)
