  // 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)
  //
