| // RewriteCubeMapSamplersAs2DArray: Change samplerCube samplers to sampler2DArray, and the |
| // textureCube* function calls to calls to helper functions that select the cube map face and sample |
| // from the face as a 2D texture. This emulates seamful cube map sampling in ES2 (or desktop GL 2) |
| // and therefore only looks at samplerCube (i.e. not integer variants or cube arrays) and sampling |
| // functions that are defined in ES GLSL 1.0 (i.e. not the cube overload of texture()). |
