Tracking of Frames, so that only one unique one can exist at a time
(gles does not allow multiple frames being rendered in parallel)
lead to very unfriendly lifetime-heavy code. A renderer is already
*unique*, just move the code there and add an error variant to catch
misuses.
- Cursor is not necessary anymore as rendering hardware vs software
cursors just depends on "where" you render the cursor.
- Format is replaced by drm-fourcc and more related to buffers and
therefor the allocator module anyway.
- GL/Glium are replaced by the renderer module.
- Software was unused and very small anyway and can be implemented
with the new renderer api.
- SwapBuffersError is (for now) just moved into the top-level backend module.
This pulls a lot of code from anvil/src/glium_drawer and replaces glium
as glium has too many assumptions about the backend.
(Mostly that a fixed framebuffer exists, see fix bullet point.)
Depending on how picky glium is, we could try to re-introduce glium support
later with a some workarounds, but for now this is actually more
straight-forward to support and test.
- Add a new GL renderer, that only depends on egl as an initialization platform.
In particular do not depend on a surface being available.
Renderers share some basic drawing functions and may bind objects to render upon.
E.g. surfaces or buffers, textures, etc for the gles2 renderer.
- Be explicit about extensions we require and use. Use some very very common ones
to make our lives easier (e.g. BGRA and unpack to read in manditory shm formats).
- Enable GL debug output
- Allow more flexible rendering (e.g. 3D compositors) by allowing user-provided
projection matrices. Also provide helper functions to allow easy-ish handling
of surface and output transformations.
- Add API for renderers to tell the wayland-frontend about supported buffer-types.
- Also incoperate code from anvil/src/shm_load to handle buffer loading in the renderer
(as this is a renderer dependant operation).
- Remove EGLStream code, nvidia support will re-introduced,
when 470 hopefully lands with GBM support this summer.
- Greately simplify the native code by setting exclusively on
`EGL_EXT_platform_base` and its extensions for initialization.
- Remove generic parameters for the underlying objects on `EGLDisplay`
and `EGLSurface` by using trait objects instead.
- Allow creation of `EGLContext`s without a config for surface-less usage.
- 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).
- Add module that deals with different kinds of buffers (memory and external),
their allocation and usage for rendering. Also try to properly support modifiers this time.
- Describe gbm functionality as an allocator (instead of a rendering device/surface).
- Also create a quick-and-dirty dumb buffer allocator for tesing / simpler tasks.
- Add a (current untested) wrapper for dmabufs and some code for converting from gbm for now.
- (also untested) Swapchain helper to manage front/backbuffers for surfaceless rendering.
It is not necessary to set the cursor position on winit since the
windowing system already updates the position on its own. Instead, doing
this makes the cursor (almost) stuck and unmovable. Thus, this commit
just removes that code from the winit backend.

libinput provides sub-pixel precision for pointer motion & touch events.
Keep this precision by switching all coordinates values from input
events to f64 (rather than i32 or u32). Otherwise, values are rounded
and part of the movment is lost.
Potentially fixes#224
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.
Introduce the `backend_session_elogind` cargo feature which pulls
`backend_session_logind` and makes the logind session backend seek
`libelogind.so` instead of `libsystemd.so`.
Fixes#127
Rework the Session Notifiers so that they are calloop event sources
by themselves, allowing them to be inserted by the user without the
`bind_session` dance.
Also update the logind backend to use the current dbus-rs API, rather
than the deprecated one.
