Ok now only Blue Noise Dithering left to do and we're ready to merge ;)

[AnastaZIuk]

I think we should move IDither to asset directory

@devshgraphicsprogramming I'm done

CBlitFilter has worked with new API recently correctly without issues but I wonder if we should query the seed for wang hash in the way like I do it now (maybe we should change it to something like std::chrono::high_resolution_clock::now().time_since_epoch().count() or similar?)

spotted an issue however! it seems it isn't due to dithering - when using Identity dither it generates the same weird output on bottom and right EDIT: it's probably a bug https://github.com/buildaworldnet/IrrlichtBAW/issues/460#issuecomment-683741305

seed should be in the whitenoise dither's state
