+// 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)
+//
