Replace Clutter.Image usages with plain CoglTexture

[bilelmoussaoui]

Currently, the code uses Clutter.Image just for it capacity in creating a CoglTexture for you. Instead, please replace it with either using St.ImageContent (not really a solution, just working around ClutterImage being merged with StImageContent in the future).

Or ideally, replace the places where you create a ClutterImage to get the texture by creating the Cogl.Texture manually yourself.

The code does basically

  ClutterContext *context = _clutter_context_get_default (); // Replace with getting the context from the actor
  ClutterBackend *backend = clutter_context_get_backend (context);
  CoglContext *cogl_context = clutter_backend_get_cogl_context (backend);
  CoglTexture *texture_2d;

  texture_2d = cogl_texture_2d_new_from_data (cogl_context,
                                              width,
                                              height,
                                              pixel_format,
                                              row_stride,
                                              data,
                                              error);

Thanks for the hint! So Clutter.Image will be gone with GNOME 48? I'll have a look at it.

Yes https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/4133, you can also just use StImageContent if you want to be "lazy"

Ok! Then thanks a lot for the warning 😅
