Support for showing images in background/foreground and only in perspective/orthographic view. Internally the depth of the image is modified in the fragment shader by setting `gl_FragDepth` explicitly. The UI still needs some work to improve usability, see D3863 for details. Currently there is one duplicated function, not sure how to best deduplicate it yet.
