When integrating wlroots with another toolkit, wlroots may receive
wl_pointer.enter events for surfaces not backed by a wlr_output.
Ignore such surfaces by tagging the ones we're aware of with
wl_proxy_set_tag().
since wayland doesn't provide a touch id in cancel events, track what
points are active so we can cancel all of them
timestamp is also not provided - use 0 because no one's paying attention
to that anyway
Closes#3000
Instead of destroying all seats, destroy a single one. We only need
to destroy all seats at one call-site (backend_destroy), but we'll
need to destroy a single seat elsewhere in the next commit.
We were firing the new_input signal on backend initialization,
before the compositor had the chance to add a listener for it.
Mimick what's done for wl_keyboard: if the backend hasn't been
started, delay wl_touch initialization.
Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3473
All the code logic related to the pointer has been moved to its own file.
The seat is responsible for the lifetime of its wlr_wl_pointer(s), and assigning
them to the relevant wlr_wl_output. The wlr_wl_pointer becomes a simple helper
to manager the wlr_pointer associated to the seat's wl_pointer and its lifetime.
This field's ownership is unclear: it's in wlr_input_device, but
it's not managed by the common code, it's up to each individual
backend to use it and clean it up.
Since this is a backend implementation detail, move it to the
backend-specific structs.
There's no guarantee that the parent Wayland compositor uses
CLOCK_MONOTONIC for reporting presentation timestamps, they could
be using e.g. CLOCK_MONOTONIC_RAW or another system-specific clock.
Forward the value via wlr_backend_impl.get_presentation_clock.

Instead of passing a wlr_texture to the backend, directly pass a
wlr_buffer. Use get_cursor_size and get_cursor_formats to create
a wlr_buffer that can be used as a cursor.
We don't want to pass a wlr_texture because we want to remove as
many rendering bits from the backend as possible.
Every host seat with pointer capability propagates events to one of
sub-pointer depending which output window we entered.
active_pointer tracks reference to sub-pointer on enter/leave events to
avoid lookup for it on every move events.
Fixesswaywm/wlroots#1499
Check that buffer can be scanned out in wlr_output_test instead of
wlr_output_attach_buffer. This allows the backend to have access to the
whole pending state when performing the check.
This brings the wlr_output API more in line with the KMS API.
This removes the need for wlr_output_attach_buffer to return a value,
and for wlr_output_impl.attach_buffer.
Previously, we just assumed submitting a new frame would make the
compositor release the current one. This isn't always the case, for
instance Sway retains old buffers when a transaction is pending. This
resulted in synchronization issues with clients writing in
front-buffers.
Fix this by un-referencing a wlr_buffer when the parent compositor sends
wl_buffer.release.
Tested by running a fullscreen mpv instance in Sway with the Wayland
backend.
We just send relative motion events alongside absolute motion events.
Compositors can figure out how absolute and relative events are related
(e.g. whether they have been triggered by the same logical event) with
the frame event.
