Making anchor's matte solid white

There are some scenarios when after step 1 anchor's matte is not solid white. Use White Level to correct this.
Example of situation where we have perfect black background's matte but not solid anchor's matte.
To help this move White Level slider to lower position.
Of course if the colour on anchor will be too similar to the background colour, probably even White Level slider won't
help because it will cause the background to be also visible again.
The idea of this step is to try to get solid anchor's matte without losing perfect black on the background.
If it proved to be impossible then the last chance is to work with Tolerance sliders.
Now we solid white anchor's matte and have perfect black background's matte.
The main rule on working with sliders is to get the best results with moving it as less as possible. So if user is able to
achieve solid anchor's matte on different ways, the one with the lowest slider's movement should be chosen
