// 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()).
