| // 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) | |
| // | |
