Polygons by Kochubey

I think this is cool and well done idea, I like it and is very good how is done the shading and good lighting, and the shadows, and how it works when using the "size pixels" slider

But still do not know to use it right, I mean how does the filter pick the colors from the source image? Because is weird the result, considering that the default thumbnail is taken from the FF lifesaver.

When opening the filter I have seen that the source image is reduced much and only takes the a small part of the center of the source image as source colors, but then they are scattered.

Also I wonder why there is no option to make the polygons fill all the screen in the same way as when you uncheck the "flat background" checkbox but instead of filling it with white it would be filled with the source image colors, I mean to have a switch and checkbox to remove the frame component if wanted.

I think that this has been developed to be shown like "flying" polygons or suspended in air, but it could have also the option if wanted to have also the full screen polygons with full colors source.
