Bug#996691: cogl: no new development upstream

[Simon McVittie]

Source: cogl
Version: 1.22.8-3
Severity: important
Tags: bookworm sid upstream wontfix

The upstream README says:

> Clutter is in deep maintenance mode; only micro releases addressing
> bug fixes are planned from now on. Additionally, the API and features
> are frozen.
>
> The planned replacement for Clutter is GTK 4.0.

This applies equally to cogl. GTK 4 has its own scene-graph layer, GSK,
which is a replacement for Clutter and does not require cogl.

(This does not apply to the vendored/internal fork of cogl and Clutter
in the mutter source package, which is gradually being subsumed into the
mutter codebase.)
