// ANTIALIASED PIXEL ART SAMPLING EXAMPLE

//old code by Robert Cummings, thanks to Ben Golus for the original techniques + the internets etc (this isn't copyrighted code!)
//all this code is considered open source - do what you want, just don't bother charging for it, share with people
//each texel is a flat plateau of solid colour. 
//blending  occurs at transition band at texel borders, sized to cover one screen pixel, no shimmer/blur/crawl etc...
//this effectively turns the bilinear filter into a box filter exactly one screen pixel wide, centered on the texel boundary.
//texture and sampler should use BILINEAR filtering + CLAMP or WRAP as needed, no mipmaps!!! 
//point filtering will NOT work
//should work with on UE (custom nodes), Unity, Godot / most engines with a few tweaks
