This allows wlroots based compositors to properly use graphic tablets
with the wayland backend.
This should be a decent quality of life improvement when working on
tablet related features.
Instead of checking that the path property is not 0 to determine if the
connector is an MST connector, check if the path contains the mst:
string.
Fixes#1813
libinput_event_touch_get_slot always returns -1 for single touch devices. Using
libinput_event_touch_get_seat_slot instead ensures that they are assigned actual
slot ids.
Also, this is what Weston does, so this change yields a more consistent
behaviour between different compositors.
Instead of waiting for the next pageflip, destroy the output immediately
since we can now handle flips for outputs which no longer exist.
Also demote the missing crtc on flip to debug.
Fixes#1739
This commit makes more output properties (mode, enabled, scale and transform)
atomic. This means that they are double-buffered and only applied on commit.
Compositors now need to call wlr_output_commit after setting any of those
properties.
Internally, backends still apply properties sequentially. The behaviour should
be exactly the same as before. Future commits will update some backends to take
advantage of the atomic interface. Some backends are non-atomic by design, e.g.
the X11 backend or the legacy DRM backend.

The documentation for wayland-server.h says:
> Use of this header file is discouraged. Prefer including
> wayland-server-core.h instead, which does not include the server protocol
> header and as such only defines the library PI, excluding the deprecated API
> below.
Replacing wayland-server.h with wayland-server-core.h allows us to drop the
WL_HIDE_DEPRECATED declaration.
atomic and legacy now both pass the backend as the user data for the
pageflip event. We than retrieve the correct connector by matching on
the crtc_id passed to the page_flip_handler2.
Wlroots also requires the DRM_CRTC_IN_VBLANK_EVENT capability now.
Fixes#1297
The backend doesn't need to handle transform changes, since everything is done
in software. In fact, all of the implementations were all identical and just
set the transform.
We could add support for hardware transforms, but:
- This would require a different field (something like hardware_transform)
- Not all combinations are possible because there often are hardware
limitations
- The Wayland protocol isn't ready for this (in particular xdg-output, see [1])
This belongs to a different patch series anyway.

The DRM subsystem needs a NULL modeset for connectors which disappear
from the system to disable the hardware pipes, otherwise the pixels get
rendered but are sent nowhere.
The atomic backend does the equivalent by removing the properties and
issuing a commit.
Fixes#1706
In order to support compositors running as systemd user units without display manager,
a mechanism for specifying session ID exactly must exist.
Checking for `XDG_SESSION_ID` mimics loginctl behaviour e95be7def2/src/login/loginctl.c (L856).
"/org/freedesktop/login1/seat/self" path triggers seat-finding code path in logind,
which currently relies on getting the session based on caller's PID.
This behaviour is deprecated in logind as it doesn't work eg. with systemd user units,
which run outside of user session.
We check for "seat0" in logind_change_vt() already as introduced in 47985d2dc5,
so hard-coding it here is not a problem, otherwise sd_session_get_seat() could be used.
When using the rdp backend and connecting with xfreerdp ... --rfx, wlroots
crashes in backend/rdp/output.c while attempting to realloc(..., 0).
This commit guards against that and instead returns true, resulting in
no rfx message being sent. This prevents the crash and appears to work, but
it's not obvious if this is correct from a specification perspective.
This appears to be a quick fix for compositors freezing when a dock is
disconnected. Disconnection of the dock is causing `pause_device` for
the DRM devices associated with the dock. Since these devices major
number is `DRM_MAJOR`, the session was being set to inactive. This just
makes it so the session is not set to inactive when the device's state
is `gone`.
This updates the backend part of the output API. This is mostly renaming:
make_current becomes attach_render and swap_buffers becomes commit.
This also fixes the RDP backend to support NULL damage.
The deleted includes are redundant, because other headers will include
the necessary files. Additionally, they cause build failures, because
including EGL/egl.h or EGL/eglext.h directly, instead of through
wlr/render/egl.h or wlr/render/interface.h, will mean that
MESA_EGL_NO_X11_HEADERS will not have been defined, and so the EGL
headers will attempt to pull in unnecessary X11 headers that may not
exist on the system.
For the headers produced by glgen.sh, the includes couldn't simply be
deleted, because no other header would include the EGL headers. Neither
wlr/render/egl.h or wlr/render/interface.h felt appropriate to include,
so I opted instead to copy the MESA_EGL_NO_X11_HEADERS definition before
the EGL includes.
