Major speed enhancement of yuvscaler by a factor 2 to 4.
I personnally very strongly suggest to upgrade to this version.

bump micro version to 3 now that 1.6.2 is released.

release 1.6.2, back merged from trunk.

release 1.6.2

Described the new -s option (to skip frames), and fixed some typos.

Added a new option, "-s num", to allow beginning frames to be skipped.
The first num frames are written to stdout unmodified. This is useful
for resuming an interrupted process without duplicating work.

Changes to the man page, to correspond with my recent modifications to
yuvmedianfilter (and to fix some typos).

Added several options.

-I num: override the interlacing value read from the YUV stream.
-s num: Allow the first num frames to be skipped. Those frames are
written to the YUV output stream unfiltered.
-f: "Fast" filtering. The threshold-based averaging is not done;
instead a simple mean is calculated, much like what happens when
not enough values in the radius are within the threshold.
-w num: In fast mode, the weight to assign the current value, relative
to the values within the radius. Default is 8, just like in
the threshold-based version when not enough values are within the
threshold.
Note that certain combinations of radius/weight have been optimized
to be even faster -- radius 1 and weight 2.667, radius 1 and weight
8, and radius 2 and weight 8.

Code freeze is over (release yesterday), add the spatial filter submitted by
Dan Scholnik.
