Update page to match HistogramAdjust

Mjb: it seems parameter w should be mf, and something should be said about the name change. nothing else checked

+[[HistogramAdjust]], adjusts the histogram of a frame by either equalizing it or by matching with histogram of another image, or with given histogram table of values.
-This function, formerly named HistogramAdjust but now named TweakHist, adjusts the histogram of a frame by either equalizing it or by matching with histogram of another image, or with given histogram table of values. [http://www.avisynth.nl/users/vcmohan/modPlus/TweakHist.html Full Description]
+If matching with given table values, then matching clip need not be specified. The second parameter is a table of integer pairs.Each pair consists of Luma (intensity) value and the second number is population (type = 4) or cumulative population (type = 5) at this value.The table is normalized by the plugin and so approximate values are OK. Due to limitation of number of parameters that can be input through AviSynth, not more than 25 pairs can be specified. It will be possible to input by table any desired histogram shape. The plugin linearly interpolates and extrapolates to construct a full normalized histogram from these values. In case of RGB input the selected color histogram is adjusted. For other formats Y value histogram is adjusted.

 == Requirements ==
-* AviSynth+ r2347 or greater
+* [x86]: [[AviSynth+]] or [https://sourceforge.net/projects/avisynth2/ AviSynth 2.6]
-* Source video: Progressive
+* Supported color formats: [[RGB24]], [[RGB32]], [[YUY2]], [[Y8]], [[YV12]], [[YV16]], [[YV24]]
