AntiBlink(minvar=[0...255],accuracy=[0...8],debug=[true..false],lumamin=[0...255])
Antiblink(15,3,false,16)

No default, so set all options.

the rainbow artifact can be considered as a chroma value oscillating (hence the blink) around the
good value.

minvar is the minimum value of the amplitude of the variation. setting it low may not catch all blinking because of the next parameter.

accuracy tells how close to a real oscillation it must be.
Let's say the chroma value follows this variations: 94-175-98-173
the amplitude (minvar) is then 78: 81 and 75 (v2-v1 and v4-v3)
accuracy=1 tells that the variation in this amplitude can be 0.5*78 = 39 (quite away from a true oscillation)
accuracy=2 would be 0.25*var
accuracy=n would be 1/(1+n)*var

debug=true/false
display the matches in green if set to true

lumamin is to skip work on dark pixels (where it's not visible or hardly).
