		+
		+	== Description ==
		+	[[ColourLike]] makes a clip look like a 'reference' clip by adjusting each colour channel.
		+	<br>
		+	It also has a polar-YUV mode, which as its 3 channels has
		+	:1) Y,
		+	:2) Length of the UV-vector (saturation)
		+	:3) Angle of the UV-vector. (hue)
		+	Currently the angle is not changed by the filter (ie does not change hue).
		+
		+	Be careful to feed the filter with the right kind of histogram... YUV, RGB and Polar-YUV are three different kinds.
		+
		+
		+	*Note: Documentation below are mostly words of author mg262, but edited from various posts on doom9 and had some text inserted to either clarify or denote usage.<br> Edited by StainlessS, on [https://forum.doom9.org/showthread.php?p=1582935#post1582935 Doom9 Forum]

		+	== Requirements ==

		+	* Supported color formats: [[RGB32]], [[YV12]]

		+	WriteHistogram(clip,string outputfile, int "every"=1)

		+	Computes histograms for each channel of the clip and stores the results in outputFile.
		+	If e.g. every=3 is specified, only every 3rd frame of clip is sampled.
		+	# Returns original clip (No Constructor)
		+
		+

		+	WritePolarHistogram(clip,string outputfile, int "every"=1)
		+	YV12 Only, Emits a "Requires RGB32" message if NOT YV12 ???
		+	Computes polar histograms for each channel of the clip and stores the results in outputFile.
		+	If e.g. every=3 is specified, only every 3rd frame of clip is sampled.
		+	# Returns original clip (No Constructor)

		+	Copy a Polar histogram ie make duplicate file.

		+
		+	ColourLike(clip source,string sourceHistogramFile,string referenceHistogramFile, \
		+	bool "affectfirst"=true, bool "affectsecond"=true,bool "affectthird"=true)
		+	YV12, RGB32
		+	Takes a clip source and histogram files for this clip and a reference clip, and applies curves to each channel
		+	chosen, to make source look as much like the reference as possible.
		+
		+
		+	PolarColourLike(clip source, string sourceHistogramFile,string referenceHistogramFile, \
		+	bool "affectfirst"=true, bool "affectsecond"=true,bool "affectthird")
		+	YV12 Only # RGB32, Not implemented for RGB32 depite error msg saying YV12 & RGB32 only
		+	Takes a clip source and histogram files for this clip and a reference clip, and applies curves to the clip,
		+	to make source look as much like the reference as possible.
		+	affectfirst, affects Y channel
		+	affectsecond, affects length of the UV-vector (ie SATURATION)
		+	affectthird, if supplied is IGNORED, (angle of the UV-vector) (ie Does not change HUE)
		+	The first true tells the filter to affect luma, and the second true tells it to affect saturation.
		+
		+
		+	ApplyAMP(clip, string CurveFilename)
		+	YV12, RGB32
		+	Affects Y channel only for YV12
		+
		+
		+	SaturationGamma(clip, float gamma, float "fixed"=127.0)
		+	YV12
		+	Affects U & V channels Only (applies gamma to length of the UV-vector [SAT])
		+	Y channel untouched
		+	I've also added a saturation gamma function. The idea is this. A normal gamma operation can brighten or darken
		+	midtones while (approximately) leaving highlights and shadows alone. The saturation Gamma can increase or decrease
		+	the saturation of areas with medium saturation, while leaving greys and very saturated areas alone.
		+	The fixed parameter gives a "very saturated" saturation level [measured as a distance from (128,128)] that will
		+	be left alone by the function... but it will work fine if you leave this number at default.
		+	The results are (in my view) quite interesting, so do give it a go!
		+	</pre>
		+	<br>
		+	== Examples ==
		+	<pre>
		+	Here are some examples from a case where the same clip is present in (unrelated) DVD and VHS sources.
		+
		+	First generate the histograms:
		+
		+	dvd.WriteHistogram("dvd hist 100.txt", 100)
		+	vhs.WriteHistogram("vhs hist 100.txt", 100)
		+
		+	Then, say, adjust the VHS to look as much like the DVD as possible:
		+	vhs.colourlike("vhs hist.txt", "dvd hist.txt")
		+	or
		+	vhs.colourlike("vhs hist.txt", "dvd hist.txt", true, false, false)
		+	which means: just process Y (respectively R) but ignore U and V (respectively G and B).
		+
		+	Or adjust the DVD to look as much like the VHS as possible
		+	dvd.colourlike("dvd hist.txt", "vhs hist.txt")
		+
		+	Polar:
		+	dvd
		+	WritePolarHistogram("dvd polar hist 1.txt", 1)
		+	vhs
		+	WritePolarHistogram("vhs polar hist 1.txt", 1)
		+
		+	dvd.polarcolourlike("dvd polar hist 1.txt", "vhs polar hist 1.txt", true, true, true) #last 'true' is ignored
		+
		+	The first true tells the filter to affect luma, and the second true tells it to affect saturation.
		+	This should in theory change the brightness, contrast, saturation, etc but not affect hue.
		+	I haven't found this to be very useful in practice.
		+	I think a variant which changed hue would be more useful, but this is ill-defined... or more precisely,
		+	because hue is represented by a circle rather than a line, there is a whole family of 'hue-equalising' filters...
