+- [ ] Rewrite libimagerror to be based on `chain-error` crate. This basically
+  removes our error infrastructure, though existing traits and convenience
+  functionality should be kept (for example the `MapErrInto` or the `IntoError`
+  traits), as much as possible). If the switch to `chain-error` would require
+  too much code to be rewritten, reconsider.
