For three-dimensional textures, the z index refers to the third

|
dimension. For two-dimensional array textures, the z index refers to

the slice index.

This region may not include any texels outside the range of the

texture array as it was originally specified.
|

It is not an error to specify a subtexture with zero width, height, or
|

depth but such a specification has no effect.
