compositor_accumulate_damage() is called for each output during repaint.
The DRM backend will only set keep_buffer for the surfaces that are visible on
the current output. So a buffer_ref is released that may still be needed. When
the output that shows the surface is repainted, the buffer_ref is gone and the
surface cannot be put on a plane.
Ignore all surfaces that are not visible on the current output to avoid this.

Currently the debug output for 'drm-backend' can be confusing. In the output of
debug_scene_view_print() views may be listed as 'not opaque' but later, during
plane assignment, other views underneath such a view is reported as 'occluded on
our output'.
This happens because weston_view_is_opaque() has some extra checks to determine
if a view is fully opaque, such as 'is_opaque' provided by the renderer for
formats that have no alpha channel.
Use weston_view_is_opaque() in debug_scene_view_print() as well to get more
accurate results.

This moves the creation of the blob to be earlier, to when the damage is
calculated. It replaces the damage tracked inside of the plane state
with the blob id itself.
This should stop creating new blob ids for TEST_ONLY commits, and them
being leaked in general, as the blob ids are now freed with the plane
state.
The FB_DAMAGE_CLIPS property is now always set if it's supported, and
will be 0 in the case that we have no damage information, which

In the test suite we may want to run a DRM-backend test on a
non-default seat, which may not have a input device associated.
Weston's default behavior is to not open if input devices are
not found, as it may cause troubles. For instance, Weston can
open but if no input device is set than the user can not
interact or leave it.
Add flag --continue-without-input to DRM-backend so we can run
these types of tests with no input. Notice that this won't force
the compositor to skip opening a input device if it finds it on
the non-default seat.

All timeline event timestamps are in CLOCK_MONOTONIC already. DRM KMS
timestamps are practically guaranteed to be CLOCK_MONOTONIC too, even though
presentation clock could theoretically be something else. For other backends,
the presentation clock is likely CLOCK_MONOTONIC_RAW due to
weston_compositor_set_presentation_clock_software().
This patch ensures that the recorded vblank timestamp is in CLOCK_MONOTONIC.
Otherwise interpreting the timeline traces might be difficult to do accurately,
since it would be hard to recover the relationship between the presentation
clock and timeline event timestamps.
The time conversion routine is the simplest possible, I don't think we need any
more accurate conversion for timeline purposes. Besides, DRM-backend is the
only backend where the timings actually matter, the other backends are
software-timed anyway.
Since the clock domain of the "vblank" attribute potentially changes, the
attribute is renamed. Wesgr never used this attribute.

If a surface has subsurfaces then the surface itself is in the subsurface
list. To avoid printing it again there is a check to skip the child view,
if it is the same as the current view.
However, this fails when a surface with subsurfaces has two (or more) views:
The check to skip the parent fails for the other view and the two views are
printed again and again until a stack overflow occurs.
So instead check if the parent view of the subsurface view is the current
view. This way, any view that does not belong to a real subsurface is
skipped.
As a side effect, this ensures that each view of the subsurfaces is only
printed once at the correct place in the hierarchy.

The renderer buffer size is usually the same size as the current mode,
so we were taking the dimensions from the currently-set mode. However,
using current_mode is quite confusing in places when it comes to scale,
and it also hampers our ability to do mode switches, as well as to
introduce a future option which will let the renderer use a smaller
buffer than the output and display scaled.
Simply take the dimensions of the renderer's output buffer from the
buffer itself.

This condition inside drm_output_render() checks if we can reuse the
existing renderer buffer for the primary plane; this occurs in
mixed-mode composition where a client buffer promoted to a plane has
changed, but the primary plane is unchanged.
We accomplish this by checking if there is no damage on the
primary/renderer plane, and then if there is already a renderer buffer
active on the primary plane: in that case, we can reuse the buffer we
already have.
There was a further condition checking if the width and height were
identical. This was designed to prevent against issues on mode changes.
However, runtime mode changes are already quite broken, and a mode
change will also cause damage on the full plane. We can simply remove
this condition.

When weston-desktop-shell uses a solid color for the wallpaper, it creates a
1x1 buffer and uses wp_viewport to scale that up to fullscreen. It's a very
nice memory saving optimization.
If you also have output scale != buffer scale, it means pixman-renderer chooses
bilinear filter. Arguably pixman-renderer should choose bilinear filter also
when wp_viewport implies scaling, but it does not. As w-d-s always sets buffer
scale from output scale, triggering the bilinear filter needs some effort.
What happens when you sample with bilinear filter from a 1x1 buffer, stretching
it to cover a big area? Depends on the repeat mode. The default repeat mode is
NONE, which means that samples outside of the buffer come out as (0,0,0,0).
Bilinear filter makes it so that every sampling point on the 1x1 buffer except
the very center is actually a mixture of the pixel value and (0,0,0,0). The
resulting color is no longer opaque, but the renderer and damage tracking
assume it is. This leads to the issue 373.
Fix half of the issue by using repeat mode PAD which corresponds to OpenGL
CLAMP_TO_EDGE. GL-renderer already uses CLAMP_TO_EDGE always.
This is only a half-fix, because composite_clipped() cannot actually be fixed.
It relies on repeat mode NONE to work. It would need a whole different approach
to rendering potentially non-axis-aligned regions exactly like GL-renderer.

It was discovered in issue #99 that the implementations of the 90 and 270
degree rotations were actually the inverse of what the Wayland specification
spelled out. This patch fixes the libweston implementation to follow the
specification.
As a result, the behaviour of the the weston.ini transform key also changes. To
force all users to re-think their configuration, the transform key values are
also changed. Since Weston and libweston change their behaviour, the handling
of clients' buffer transform changes too.
All the functions had their 90/270 cases simply swapped, probably due to
confusion of whether WL_OUTPUT_TRANSFORM_* refers to rotating the monitor or
the content.
Hint: a key to understanding weston_matrix_rotate_xy(m, c, s) is that the
rotation matrix is formed as
c -s
s c
that is, it's column-major. This fooled me at first.
Fixing window.c fixes weston-terminal and weston-transformed.
In simple-damage, window_get_transformed_ball() is fixed to follow the proper
transform definitions, but the fix to the viewport path in redraw() is purely
mechanical. The viewport path looks broken to me in the presence of any
transform, but it is not this patch's job to fix it.
Screen-share fix just repeats the general code fix pattern, I did not even try
to understand that bit.

When using weston-launch launcher deactivating the VT is sometimes
racy and leads to Weston still being displayed. The launcher-direct.c
backend makes sure that the session signal is emitted first, then DRM
master is dropped and finally the VT switch is acknowledged via
VT_RELDISP.
However, in the weston-launch case the session signal is emitted via
a socket message to the weston process, which might get handled a bit
later. This leads to dropping DRM master and acknowledging the VT
switch prematurely.
Add a socket message which allows weston to notify weston-launch that
the signal has been emitted and deactivating can be proceeded.

On weston-launch exit we see errors such as:
failed to restore keyboard mode: Invalid argument
failed to set KD_TEXT mode on tty: Invalid argument
This has been resolved by making sure the tty file descriptor
does not get closed. However, the ioctrl's KDSKBMODE/KDSETMODE
and VT_SETMODE still fail with -EIO:
failed to restore keyboard mode: Input/output error
failed to set KD_TEXT mode on tty: Input/output error
It turns out the reason for this lies in some very particular
behavior of the kernel, the separation of weston-launch/weston
and the fact that we restore the tty only after the weston
process quits: When the controlling process for a TTY exits,
all open file descriptors for that TTY are put in a hung-up
state! For more details see this systemd-logind issue:
https://github.com/systemd/systemd/issues/989
