stb_image_resize2.h: https://github.com/nothings/stb/blob/master/stb_image_resize2.h
Much faster and better than stb_image_resize.h
Major performance increases (in degenerate cases can be >1000x faster). Now includes SIMD optimizations - for SSE2, AVX, NEON and WASM.
Bit-identical deterministic results between scalar and SIMD code, across architectures (x86, arm, wasm) and across all compilers - msvc, clang, gcc.
