issue30: wrong displayed information
Related to #30 (closed). Fixed by using the correct values. The current version query the (squared) spp from the sensor, which is not overrided by the user-specified argument.
Also, using the "-samples" argument in interactive mode is actually irrelevant and has no effect. Use "-sample_per_frame" ("-spf") to specify how many samples per pixel must be rendered at each frames.
