-- The question is : ¿ Should I use all tiles of the row registered? Well for sure there are two possibilities :
-- This code was entirely written by Julian Andres Guarin Reyes.
-- 1 . Dont register them: But for there is going to be a maximun number of columns where porpagation times are going to be

-- Ray Difussion Pipe Longitude (
 -- This file is part of JART (Just Another Ray Tracer).
-- Row Ray Difussion Time ( RRDT ) in clks: 2 + log 2 (Number of Columns) clks. 
 
-- An excellent difussion Time, but the max number of columns its limited by the platform specs.
 
-- Even it is an excellent time is not much of gain because this time is the same time of the pipe longitude, thus a result each clock is achieved anyway.
