As many people "abused" the "deflicker" filter by Donald A. Graft
for noise reduction purposes, by setting a window size of "1", I had
the idea to eliminate the (for this case) obligatory code and especially
the two-pass operation mode. As in this special case most parts of the
original code become effectively operationless, they just wasted time
for nothing. This new filter got rid of all those ineffective lines of
code, resulting in a tremendous speed enhancement, not to tell of getting
rid of the (now) useless first pass. The output of this filter is 100%
identical to the output of the deflicker filter with a window size of 1 !

BUT KEEP IN MIND: This filter is only supposed to be a denoise filter like
the deflicker filter with a window size of 1. If, for any reason, you need
a true deflicker filter, with a window size different to 1, you will still
need to use Donald A. Graft's deflicker filter in 2-pass mode.
