an unpublished Raster package was written by someone on the Ada Forum and referred to on Rosetta Code…
Did this author ever finish the package? A Rosetta Code task makes a vague reference to a package used to solve the task but mentions that it is a work in progress.
Thanks,

What’s the problem / solution that refers to `Raster`?

Thanks. I wrote that. It does say,

I abandoned that work for various reasons, though I don’t recall why. If you like,
- I can make it available on GitHub, though I will want to review it before I do, and probably may want to make changes.
- I could rewrite the code to use one of @zertovitch’s packages. That could take quite a long time, though. (I’m a bit slow.)

I was just curious whether or not you had made further progress on the package and forgot to update the Rosetta Code task or not. If you do finish the package and you are able and willing to publish it, that’s very cool. If you end up using a different package to solve the task, that’s cool as well. But there’s no judgement/expectation from me regarding this, I was just curious regarding the package availability.

I added a GtkAda/Cairo solution based on [AICWL](https://www.dmitry-kazakov.de/ada/aicwl.htm).

I added a version using [Ada GUI](https://github.com/jrcarter/Ada_GUI).
