Having the clutter backend owning and managing creates complication for implementing graceful shutdown, so move it to the real backend. Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1775>

|
|
* @short_description: A native backend which renders using EGL.
|
|
*
|
|
* MetaClutterBackendNative is the #ClutterBackend which is used by the native
|
|
* (as opposed to the X) backend. It creates a stage with #MetaStageNative and
|
|
* renders using the #CoglRenderer.
|
|
*
|
|
* Note that MetaClutterBackendNative is something different than a
|
|
* #MetaBackendNative. The former is a #ClutterBackend implementation, while
|
|
* the latter is a #MetaBackend implementation.
