-An array of two-dimensional textures. It's very much like a 3D texture, with
-two important differences: there's no filtering nor mipmapping along the third
-dimension.
+An array of two-dimensional textures. It behaves much like a 3D texture, but
+mipmapping and filtering is not applied on the third dimension. When sampling
+the texture, the third coordinate is not normalized and is rounded to the
+nearest integer to select the layer.
