Compositor code can use opaque pointer comparison to determine whether
a head belongs to a given backend. Store a backend pointer in struct
weston_head to enable the compositor to select the correct backend
specific output configuration code.
This also allows to use the backend pointer instead of the opaque
backend_id pointer to check whether a head belongs to a backend, so
replace the checks in all to_xyz_head() functions and drop backend_id.

When the new option is enabled, headless backend will draw decorations
around its outputs. This makes the actual "framebuffer" larger by the
thickness of the decorations to keep the video mode area free for
clients.
This will be needed for a future test, that will ensure that GL-renderer
will paint the output decorations correctly.
The output title is deliberately NULL, because text rendering is
unpredictable and depends on e.g. what fonts are installed in the
system. Therefore screenshot testing of any text would be really
painful, so let's avoid that.
The decorations setup code is mostly copied from wayland-backend.

Nothing in-tree uses this function, and its functionality has been
replaced with the weston-output-capture protocol extension which is
implemented in libweston core.
Users of this function should migrate to
weston_compositor_add_screenshot_authority() and replace custom
screenshooting protocols with weston-output-capture.xml installed by
libweston.

This implements the basics of the new screenshooting protocol. The
actual pixel operations will be implemented separately in the renderers
and DRM-backend.
See the previous commit "protocol: new screenshooter protocol" for why.
If DRM-backend needs more from weston_capture_task when it implements
writeback screenshooting, it will be easy to add user_data or expose
weston_capture_task::link for the backend to use. Those were not added
yet because it is uncertain what is actually needed.
The DRM-backend no-damage optimization requires special handling here as
well. See also 7f1a113c89 .

We now depend on the matrices in weston_view being correct even when the

Signed-off-by: Derek Foreman <derek.foreman@collabora.com>
When we build up a matrix from a series of operations, it's very useful
to know if the combined operations still result in something that matches
a wl_output_transform.
This adds a function to test if a matrix leads to a standard output
transform, and returns the transform if it does.
Tests are provided that check if complex series of operations return
expected results - the weston_matrix_needs_filtering function is tested
at the same time.

If a transformation matrix causes a scale, a rotation not a multiple of 90
degrees or a non-integral translation then textures rendered with
it would benefit from bilinear filtering.
This test is done in a lazy fashion by examining elements of the matrix
to check for a simple pattern that indicates these conditions are met.

This introduces a few getters to retrieve the pending state from
libweston-desktop, now just libweston, and makes use of it,
specifically get_pending_maximized to avoid sending invalid
dimensions to the client in the particular use case
set_maximized/unset_fullscreen.
These pending state getters are useful to query/poke a not-applied
yet state, and could be useful where we don't have a buffer attached
where the client might be set-up as maximized, but internally libweston
hasn't yet applied that pending state.

We have a few places where we log messages only the first time they occur.
Provide a log throttling implementation so we don't have to open code this
in all the places that need it.
Instead of just logging a single time, allow some finer control. We allow
logging of a specified number of events. Additionally, we have an optional
timeout after which the event count is reset so we can log at most N
events in M ms.
The first new event printed after the timeout expires will also include a
count of suppressed events.

Some monitors expose a selector for the kind of content that will get
displayed, allowing them to optimise their settings for this particular
content type.
I got access to such a monitor, sadly even setting it to game mode
didn’t lower its atrocious latency, but drm_info[1] reports it to be set
correctly so hopefully it’ll work better with other monitors.

This adds basic VNC protocol support using the Neat VNC library
(https://github.com/any1/neatvnc). Neat VNC depends on the AML main
loop library. The backend makes use of AML's integrated epoll backend
and connects AML via file descriptor with the Wayland event loop.
This implementation does not support authentication and hardcodes the

As things are, even when mode=current is specified on the .ini file,
a full modeset is needed (and done), which causes a very noticeable
screen blinking. That is because setting the max_bpc on a connector
needs full modesetting.
The idea here is that if mode=current on the .ini, no modesetting
should be done, so the current max_bpc is programmed into the
connector.
But if a custom max-bpc=... is specified, that will be used instead,
even if mode=current on the .ini

Everywhere we are standardising to drm_fourcc.h pixel format codes, and
using struct pixel_format_info as a general handle that allows us to
access the equivalent format in various APIs. In the name of
standardisation, convert weston_compositor::read_format to
pixel_format_info.
Pixman formats are defined CPU-endian, while DRM formats are defined
always little-endian. OpenGL has various definitions. Correctly mapping
between these when the CPU is big-endian is an extra chore we can
hopefully offload to pixel-formats.c.
GL-renderer read_format is still defined based on Pixman format, because
of the pecualiar way OpenGL defines a pixel format with
GL_UNSIGNED_BYTE. That matches the same Pixman format on big-endian but
not the same drm_fourcc.

"max bpc" property is meant for working around faulty sink hardware.
Normally it should be set to the maximum possible value so that the
kernel driver has full freedom to choose the link bpc without being
artificially forced to lower color precision.
The default value is 16 because that is a nice round number and more
than any link technology I've heard is using today which would be 12.
Also offer an API set the value, so that weston.ini could be used in the

Output color profile may be changed in flight. Output basic color
characteristics and EOTF mode cannot yet be changed in flight, but it is
reasonable to assume they could in the future. Therefore the color
outcome data may change in flight as well, which is the basis for HDR
metadata, which needs to be updated as well.
Track the changes to color outcome data with a serial number.
DRM-backend checks the serial number to see if it needs to re-create the
HDR metadata blob. This allows the changes to propagate all the way to
KMS.
The code added here is more of a reminder of what should happen than a

This adds color_chracteristics field in weston_output. This field is
intended to be set by compositor frontends and read by color managers.
Color managers can use this information when choosing the output color
space and dynamic range, particularly when no ICC profile has been set.
This is most useful for HDR outputs, where the HDR static metadata for
PQ mode or the display luminance parameters for HLG mode can be based on
color_characteristics.
The fields of weston_color_characteristics mirror the information
available in EDID. However, using EDID information as-is has several
caveats, so the decision to use EDID for this is left for the frontend
and ultimately to the end user.
There are no defined ranges or validity checks for this data. The color
manager will have to validate the values against whatever it is using
them for.
