| A fundamental limitation of the 3D plotting engine is that intersecting objects cannot | ||
| be drawn correctly. One object will always be drawn after the other. Therefore, | ||
| multiple image planes can well be used in the background as shown in this example. | ||
| But this approach is not suitable if the planes intersect. |

I think this is a good paragraph to include, this "2.5D" renderer behavior is non-obvious, and we should mention it as often as possible IMO.

Yeah, I also think this is great - it explains why this needs to be a separate example and so will be nice to link to off the intersecting example (and they can all have the same taghttps://matplotlib.org/devdocs/devel/tag_guidelines.html )

Image from the built docs:
It may be more impactful if you manually set the axlims so the images line up with the backing planes, but your call. Can self merge if you prefer as-is.

I slightly favor leaving it as is:
- Less optional configuration code keeps the example more readable
- I like that the planes are floating above the axes cube. This is a slight visual hint that the images are not tied to the cube and can theoretically be anywhere.
