// 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 http://anglebug.com/1469
