I reply to your other comments soon.

> openni2: Is it really necessary to have JRE and the JDK as REGULAR inputs?  Why?

Ah, thanks for spotting that. It is only required during build. I have
moved them to native-inputs now.

> opesles: Did not review yet.  Do we need that random commit ea5104b?  Is there a release to use instead?

Unfortunately, this project neither does releases nor tags. They just
bundle things in versioned folders.

Makes sense! Fixed it now.

Please find the attached patches that are to be applied between
rust-imgref and gtk+-2 commits.
