eec50e5aac backend-pipewire, libweston: Extract weston_output_arm_frame_timer()
Extract pipewire_output_arm_timer() into libweston so it can be reused
by the other timer driven backends that use the same delay logic.

Call the shared function weston_output_arm_frame_timer().

4d14adaa2c backend-pipewire: make sure to finish frames with timestamps in the past
Round up the ms delay to make sure that the finish_frame_timer always
expires after the next frame_time. That way, finish_frame_handler()
never passes a timestamp in the future to weston_output_finish_frame().
Setting frame_time into the future risks hitting an assert in
weston_output_finish_frame(), when it is called from start_repaint_loop
within the frame interval.

Use CLIP() to simplify limiting the ms delay to a reasonable range.

1d59530e4b libweston: Set the presentation clock in the compositor
Let backends declare the presentation clocks they can use with a
new bitfield weston_backend::supported_presentation_clocks and set
presentation clock after loading the backend in the compositor.

Make weston_compositor_set_presentation_clock() internal and replace
weston_compositor_set_presentation_clock_software() with an exported
weston_compositor_backends_loaded(), which is called by the compositor
after the backend is loaded.

In the future, this can be extended to determine the subset of clocks
supported by all backends.

f07af89f9c libweston: Move output damage subtraction out of backends
Right now every backend clears output damage from the primary plane when
it repaints. Instead of having this same operation spread across all
the backends, just do it in the core instead.

In the future, we want to remove damage tracking from the primary plane
entirely, and this is a small step in that direction.

90c11cf40e libweston: move weston_compositor_shutdown call out of backends
If we want to support multiple backends, the compositor must take care
to call this once, at the appropriate moment, so stop letting the
backends handle compositor shutdown themselves.

Move the weston_compositor_shutdown() calls from the backend::destroy
callbacks into weston_compositor_destroy() and the calls in the backend
creation error paths into weston_compositor_load_backend().

5b1974fa4f backend-pipewire: add GL renderer support
While the GL renderer is not able to directly render into the PipeWire buffers,
it is possible to read the rendered frame from the fbo into the PipeWire buffer.

Use the automatic download to add support for the GL renderer to the PipeWire
backend.

a9d1b5dc50 backend-pipewire: make renderer initialization depend on renderer
Instead of always initializing the Pixman renderer, make the initialization
dependent on the selected renderer. This makes it easier to add other renderers.

f154fbba97 libweston: consolidate 'Using GL/Pixman renderer' log message
Consolidates the 'Using GL/Pixman renderer' message emitted by the
PipeWire, RDP, VNC, and X11 backends by moving the weston_log() into
weston_compositor_init_renderer(). Only print the message after
initializing the renderer has succeeded.

This effectively adds the message to the DRM, headless, and Wayland
backends.

445ff6728b pipewire-[backend|plugin]: Add timestamps to buffers
In Pipewire and Gstreamer terminology Weston is a "live" source (as we
do not explicitly set PW_KEY_STREAM_IS_LIVE to false).
Such sources, be it compositors, cameras or microphones, usually set
the current system time as timestamps on buffers in order to make life
easier for consumers. Thus let's do so as well.

This notably helps when recording using `gstpipewiresrc` with the
`keepalive-time` property set.

2d3e170955 backend-pipewire: remove linear modifier for now
As of PipeWire version 0.3.69, the gstpipewiresrc element uses the
existence of a modifier as a trigger to select dmabuf memory, failing
caps negotiation as we don't send DMA buffers yet.

Remove the linear modifier for now, to be added back when we add dmabuf
support to the PipeWire backend. This allows testing the PipeWire
backend with current GStreamer + PipeWire.

dfa821d4c0 backend-pipewire: pass backend to weston_pipewire_output_api::create_head()
Pass the backend instead of the compositor to the PipeWire output API
create_head() method and increment the API version.

That way the backend will not have to find the backend pointer from the
compositor. This is trivial now, but in the multi-backend case would
entail iterating over all backends to find the correct one.

ebc3a22b09 backend-pipewire: add PipeWire backend
Add a separate PipeWire backend based on the PipeWire plugin. The backend
requires PipeWire 0.3.x.

The PipeWire backend can be used as a standalone-backend backend for streaming
and composing Wayland clients to PipeWire.

The backend supports the on-demand creation of heads via the
weston_pipewire_output_api_v1. It also supports per-output pixel format
configuration via a gbm-format option.

Multiple PipeWire outputs can be created by setting the num-outputs option in
the [pipewire] section.
