As wayland-backend is blitting the output decorations into the output
buffer itself, it pretends towards the pixman-renderer that there is no
decorations area. The pixman_image_create_bits() call wraps the
previously allocated buffer with an offset so that pixman-renderer will
paint in the right position.
The bug is that this pixman image was using the original buffer width
and height, instead of the composited area width and height. So the
pixman image looks too big to pixman-renderer, but the renderer didn't
care. The image being too big does risk access out of bounds in
pixman-renderer.
I found this when I was making renderers explicitly aware of the
frambuffer size and resizing, added asserts, and they surprisingly
failed. This fixes that.

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.

When an output is destroyed then the output state is freed immediately. In this
case, the plane state is only partially destroyed because it is the currently
active state. This includes the buffer reference.
Without the output, the plane will not be updated any more until it is used by a
different output (if possible) or the output returns and the plane is used
again.
As a result, the buffer reference is kept for a long time. This will cause some
applications to stall because weston now keeps two buffers (the one here and
another one for a different output where the application is now displayed).
To avoid this, do a synchronous commit that disables the output. The output
needs to be disabled anyways and this way the current state contains no
buffers that would remain.
`device->state_invalid = true` in drm_output_detach_crtc() is no longer
needed, because drm_output_detach_crtc() is called only when initialization
failed and the crtc was not yet used or in drm_output_deinit() when the
crtc was already disabled with the new synchronous commit.

noop-renderer needs to actually access the buffer content, to ensure
that the bad-buffer test works. This was previously done using a
volatile variable, but clang rightly pointed out that the variable
access had no effect (since the volatile stack variable was never read
from, and the source is not volatile), so 9b0b5b57dd changed it to be
explicitly marked it as unused to suppress the compiler warning.
Unfortunately suppressing the warning still leaves the compiler free to
optimise out the access.
Replace the variable decorations with actually using the result of the
read, so we can be really sure that it's never going to be optimised

Our positioning of override redirect windows falls apart when an
app is on the fullscreen layer, because we end up putting its
menus and tooltips beneath it. This patch raises the special
override redirect layer to be just below things like on-screen
keyboards (and, unfortunately, above things like panels).
There is no perfect way to deal with this problem, especially
for content like tooltips that don't come with transience hints.
In some cases override redirect menus could be better placed by
using the parenting/transience information provided with them
at map time, and we should probably do that at some point, but
that would still leave us with tooltips below full screen
applications, and the need for this layer change.

Currently the idle_repaint_source is removed when the output is destroyed.
This covers the most common case: When a monitor is unplugged then the
corresponding DRM output is destroyed and not just disabled.
However, outputs can be explicitly disabled by the shell. In this case the

Remove the idle_repaint_source in weston_compositor_remove_output() to fix

By moving the application of view_alpha after pre-multiplication we can
simplify main() considerably.
The cost is that for straight-alpha input or color_pipeline() we might
be doing three multiplications more than before. However,
a) the cost of running color_pipeline() probably dominates anyway, and
b) to get straight-alpha input you have to use a future Wayland
extension that probably won't be advertised without color management.
So we keep the optimization for the simple case (no color management)
while potentially incurring a small cost on the heavy case (with color
management).

When color management is disabled, the fragment shader was still first
ensuring straight alpha and then immediately just going back to
pre-multiplied. This is near-impossible for a shader compiler to
optimize out, I guess because of the if-statement to handle division by
zero. Having view alpha applied in between certainly didn't make it
easier.
That causes extra fragment computations that are unnecessary. In the
issue report this was found to cause a notable performance regression.
Fix the performance regression by introducing special-case paths for
when straight alpha is not needed. This skips the unnecessary

Currently, the opaque is discarded for all transformations other than a simple
translation, because correctly transforming the opaque area is not possible in
general.
However, there is one simple case that is probably the most common one: A fully
opaque surface that is translated and scaled. In this case the opaque area is
simply the new bounding box. So set the transformed opaque area accordingly.

If surface->is_opaque is set then we can assume that the whole surface is
opaque. In the trivial case (no transformation or translation only) this means
that transform.boundingbox is exactly the view area and is fully opaque. So it
can be used for transform.opaque.
This is important because damage calculation uses transform.opaque. Without
this, anything underneath a surface without an explicit opaque region but a
pixel format without alpha channel is drawn unnecessarily.

parse_color_characteristics() and wet_output_set_color_characteristics()
get exercised. The return value and logged error messages are checked.
Other cases test the weston_hdr_metadata_type1 validation.
These are for the sake of test coverage, but also an example of how to
test a function from main.c, and how to capture messages from
weston_log().

This is the beginnings of creating composited content HDR metadata for
the ST2084 HDR mode. The immediate goal is to allow essentially setting
the HDR metadata from weston.ini, so that it can be experimented with.
Setting an output ICC profile will stop weston.ini metadata from taking
effect, but using an ICC profile in HDR mode is an open question anyway.
maxDML, maxCLL, and minDML are set based on the assumption that we want
to make use of the full sink/monitor dynamic range.
This also adds several TODOs about how we should handle output profiles,
basic output color characteristics, and HDR metadata. Implementing these
properly will take more thought and effort.

This adds hdr_meta field in weston_output_color_outcome. This field is
intended to be set by color manager modules, and read by backends which
will send the information to the video sink in SMPTE ST 2084 mode a.k.a
Perceptual Quantizer HDR system.
Such metadata is essential in ST 2084 mode for the video sink to produce
a good picture.
The validation of the data and the group split is based on the HDR
Static Metata Type 1 definition in CTA-861-G specification.

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.

Allow the front end to register audio setup and teardown functions. These
functions should use FreeRDP's rdpsnd_server_context or
audin_server_context and set up their own handler threads.
The backend remains mostly ignorant to any audio details beyond setting up
and tearing down.

Instead of a meson option or hidden define, just run these checks always.
It is not Weston's style to add build options for specific asserts, and
currently weston's codebase is expected to always run with asserts
enabled.

Fixes: 8b167a1703 ("gl-renderer: Store EGL buffer state in weston_buffer")
There's just no good reason to do this.
The query entrypoints already tell us if we need to use
GL_TEXTURE_EXTERNAL_OES for a particular format/modifier. We also have
RGB -> YUV fallbacks which should be able to work well with TEXTURE_2D.
TEXTURE_EXTERNAL pessimises quite hard, forcing GPU-side reloads as well
as bad filtering. Allowing multi-planar formats to use TEXTURE_2D should
thus result in performance and quality improvements.

Now that we can pull everything we need from pixel-formats, go one step
further and reuse the same YUV format descriptors we use to emulate
dmabuf/EGLImage imports for SHM.
This eliminates all special-case YUV/SHM handling.

Add a new hide_from_clients flag which, if set, specifies that the
format is only for internal information and processing, and should not
be advertised for clients.
This will be used for formats like R8 and GR88, which are not useful for
client buffers, but are used internally to implement YUV -> RGB
conversion.
