In IVI, there are several displays connected to a SoC. These displays
are just driven by differential pairs (LVDS, FPD-Link, GMSL) and powered
centrally. To reduce power comsumption when user inactivity timeout
happended on the display, there is a need to cut down pixel clock from
SoC. Then, if any input events happend on the display, it should become
active again.
Currently, controlling the compositor outputs doesn't happen independently
but rather globally, and outputs repaints are based on the compositor state
This is necessary to have an API that can force the power state of an
output to off via DPMS mode while all other compositor outputs remain
unaffected.

All through weston we have code that passes int x, y or
float x, y or wl_fixed_t x, y pairs. These pairs are frequently
converted to/from wl_fixed_t and other types.
We also have struct vec2d and struct weston_geometry which also
contain coordinate pairs.
Let's create a family of coordinate vector structures for coordinate
pairs and use it anywhere we sensibly can.
This has a few benefits - it helps remove intermediate conversion
between fixed/float/int types. It lets us roll the homogenous
coordinate normalization bits into helper functions instead of
needing them open coded throughout the source.
Possibly most importantly, it also allows us to do some compile time
validation of what coordinate space we're working in.

One variant is used when a view is being positioned relative to a parent,
the other is when the view is being given an absolute position in the
global space.
This will help later when surface and global coordinates are different
data types, but for now the two functions do essentially the same thing.

This sets up monitor layout callbacks, and enables input event translation
between the RDP space and the weston desktop. The RDP backend now uses
a heads changed callback instead of the simple head configurator.
We only allow a single monitor for now, but in the future RAIL will make
use of multi-head.
As a side effect, scaling is now supported in RDP sessions.
It should be noted that due to differences between RDP and wayland
representation of their global coordinate spaces, mixing DPI leads to
RDP monitor layouts that can't properly be represented in weston.

Similar to the backend type, also expose the renderer type enum as ABI.
This makes it possible to implement a more consistent config API, as
opposed to every backend hand-rolling its own use-the-other-one bool.
The enums are explicitly numbered to avoid 0, so 0 can be used as a
'not-specified' sentinel value to allow backwards compatibility with the
old config interfaces.

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

screenshooting protocols with weston-output-capture.xml installed by
libweston.
Signed-off-by: Pekka Paalanen <pekka.paalanen@collabora.com>
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 .

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
