     @ref Trade::PhongMaterialData::commonTextureCoordinates() exposing a

+-   Added @ref Trade::TextureType::Texture1DArray,
+    @relativeref{Trade::TextureType,Texture2DArray} and
+    @relativeref{Trade::TextureType,CubeMapArray} in order to be able to

+    with filtering along Z or if it's a 2D array with discrete slices.
