It was only used by OpenEXR and Iris images, and saving the Z Buffer in those formats was disabled by default. This option comes from the times prior to the addition of the Multilayer EXR. It also worth noting that it was not possible to save Iris with Depth pass from Blender as internally it is called IRIZ format and it was not exposed. But even after exposing this format option something still was missing as saving and loading ITIZ did not show up the Depth pass. The reason of removal is to make it a more clear match of the ImBuf with a render pass, and use it instead of a custom type in the render result and render pass API. This will simplify the API and also avoid stealing buffers and making shallow copies when showing the render result. For the cases when Depth is needed a Multilayer EXR is to be used, as most likely more than just the Depth will be needed. On a user level this change: - Removes the "Z Buffer" option from the interface. - It preserves existing sockets in compositor nodes, but it will output black image. Also changing the image data-block will remove the socket unless a Multilayer EXR with Depth pass image is selected. - Removes "Depth" socket of the Viewer and Composite nodes.
