: <dfn>imageHeight</dfn>
::
The pitch (measured as a multiple of {{GPUBufferCopyView/rowPitch}} bytes)
between different `z` values of the target texture.
For {{GPUTextureDimension/3d}} textures, `z` refers to the texture's depth.
For {{GPUTextureDimension/2d}} textures, `z` refers to the texture's array layers.

An `imageHeight` of zero is only valid for copies with a `copySize.depth` of 1.
