- renderer: Change the renderer api to not import different buffer types directly,
but import any supported wl_buffer
- renderer: Remove destroy_texture call and move responsibility into implementation
- gles2: Cache egl images as well as textures on wl_buffer userdata
- gles2: Implement delayed destruction of textures to avoid leaking or changing global state on drop
- Remove the `Device`, `Surface`, `RawDevice` and `RawSurface` traits.
We are not trying to merge the different responsibilities between...
- Drm-Surfaces: crtcs and planes for displaying buffers
- Gbm-Surfaces: allocating and managing front- and back-buffers
- EGL-Surfaces: Load drawing apis.
..anymore.
- Instead unify the legacy and atomic backends into one `DrmDevice` and
a `DrmSurface`, that under the hood dispatches onto the different modules.
- Do not keep a list of surfaces inside the devices. These are reference-counting
nightmares and a frequent issue due to the read-only nature of `Rc` and `Arc` and
thread-safety related problems.
- Surfaces are mostly doing state-tracking independently of each other
and contain some more helper functions.
- Simplify session code, because we do not need to pass the events
through three layers of devices and surfaces anymore.
- Each surface now represents a plane. Rendering to a plane is just like
any other rendering step, including the Cursor-plane.
(Legacy interfaces only have one to avoid dealing with short-comings of the api).
slog-stdlog has a significant dependency tree and is basically unsued if
the downstream crate of Smithay always provides a logger (like anvil),
so it is not really needed.
Change the session backend to rely on Signaler to propagate its
signals. Also introduce the Linkable trait to allow generic composition
of objects needing to listen for signals.
