- Make Texture a parent GObject class and move the vtable funcs as vfuncs instead of an interface as we would like to have dispose free the TextureLoader. - Make the various texture sub-types inherit from it. - Make all the sub-types constructors return a CoglTexture instead of their respective specific type. As most of the times, the used functions accept a CoglTexture, like all the GTK widgets constructors returning GtkWidget. - Fix up the basics of gi-docgen for all these types. - Remove CoglPrimitiveTexture as it is useless: It is just a texture underhood. - Remove CoglMetaTexture: for the exact same reason as above. - Switch various memory management functions to use g_ variant instead of the cogl_ one Note we would still want to get rid of the _cogl_texture_init which is something for the next commit Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3193>
