// This mutating tree traversal works around an issue on the translation
// from texelFetchOffset into HLSL function Load on INTEL drivers. It
// works by translating texelFetchOffset into texelFetch:
// - From: texelFetchOffset(sampler, Position, lod, offset)
// - To: texelFetch(sampler, Position+offset, lod)
// See
