Great, seems like you are making progress.

We intend to update GtkAda to 3.22 in the coming months. Apparently, this comes with a new GtkGlArea
widget directly as part of it, so this might also give us a way forward, depending on how they implemented
it and whether it is compatible with Windows and OSX.
