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