Title: slightly improve the ChromaKeyFilter

Hi Bernhard,

Here is a small improvements for my little ChromaKeyFilter.
Mainly : try to improved the semi transparent pixels and expose more configuration in the constructor.

Still not perfect for semi transparent pixel though.
But it start to be usable for image where the green screen is contrasted enough.
