The "paint" signal of ClutterActor is deprecated and will be removed. We have a good replacement to get notified about stage paints nowadays, that is "after-paint" on ClutterStage, so switch to that signal where it makes sense. I didn't bother to update the few tests (namely Clutters conform/texture-fbo.c, conform/text-cache.c, interactive/test-cogl-multitexture.c and Cogls conform/test-multitexture.c, conform/test-texture-mipmaps.c) where it's harder to replace the signal since we don't build those anyway. https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1522
