There seems to be some demand from input methods to be able
to style different parts of the preedit string differently.
Since the reasons to do that are many, and vary between IMs
and languages.
But even though some IMs would much want to be able to specify
colors, they lack the context to know what choice of colors
provides enough contrast and legibility embedded on foreign
UIs (e.g. accounting things like themes, accessibility, ...).
There is a proposal for a semantic closed list of pre-edit
styling options at https://github.com/ibus/ibus/wiki/Wayland-Colors,
which this commit follows, so clients and UIs have more freedom
in displaying a suitable style to pre-edit strings.

These requests allow clients to explicitly declare the desired
interaction pattern with input panels (e.g. the system OSK).
This allows clients to decide a fine grained pattern to show/hide
these panels that is decouple of enable/disable requests.
This may help them enhance the experience with e.g. selecting
text, or navigating around large bodies of text without an
intrusive OSK, or implementing other UI patterns like a "show OSK"
button.

In some environments it is desirable to show an input panel UI (e.g. OSK)
that is able to perform miscellaneous actions other than inserting text.
Add the framework for this, the available actions may be extended in later

The new hint is meant to indicate that the text input already provides an
on-screen means to enter data, and that using the system provided input
method may not be needed.
It should be used when the client presents the user with a custom on-screen
input method, like an on-screen keyboard, or perhaps a dropdown list.
The new hint is meant to address the issue when the system input method is an
on-screen keyboard. Without the hint, the input method would not know that it's
not needed, unless the client refrained from using the input method protocol
at all.
With the hint, the input method can still be enabled, while not displaying a
second on-screen keyboard. This allows for the system input method to still
provide accessibility services, as well as text completion or prediction.

For a variety of cases it's desirable to have a method for negotiating
the restoration of previously-used states for a client's windows. This
helps for e.g., a compositor/client crashing (definitely not due to
bugs) or a backgrounded client deciding to temporarily destroy its
surfaces in order to conserve resources.
This protocol adds a method for managing such negotiation and is loosely
based on the Enlightenment "session recovery" protocol which has been
implemented and functional for roughly two years.
v2: Address review comments
v3: Add xdg_toplevel_session_v1.restore event. Move delete toplevel
request to xdg_toplevel_session_v1. Remove surface argument from
xdg_toplevel_session_v1.restored. Remove unused 'invalid_restore'
(same intent as 'already_mapped'). Add 'invalid_session_id' error.
Specify size limits and other documentation improvements.

Synchronization is only needed for 3 things:
- to let the input method know when its update was applied not like it expected,
- especially when a byte index stopped being on bytes boundary due to extra change and a retry is needed,
- to break off events coming to an old text input after focusing a new one.
The one big change of this is relaxing the contract of the input method. The application now doesn't apply the changes exactly.
"delete_surrounding_text" is the only affected place so far, now it mentions the unexactness explicitly. The change is necessary because without strict sync, the input method can't know if it's sending messages aligned on code point boundaries.
This solves 90% of the retry problem.
Such problems all stem from text changing near the caret, where the user already has an expectation of weird interactions (multi-user typing over each other - IME garbage in, text garbage out), or the user expects something that the input method can't correct (text to emoji substitution should not result in a retry due to unexpected output, making this work with IME is the client's problem).
The other big change is keeping sync for the purpose of switching text fields.
Hopefully this is enough for everyone, and it stays more or less compatible.

This protocol provides a way for clients to create and add windows to
"zones".
A zone is a isolated environment with its own coordinate space where
clients can add and arrange toplevels that logically belong to each
other.
It provides means for, among other things, requesting that windows are
placed at specific coordinates within the zone coordinate space.
The protocol includes a request to retrieve the extents of the
server-side frame, so that it may be taken into consideration when
positioning server-decorated windows relative to one another.

When clients create an xdg_toplevel_decoration object, they opt-in for
being self-decorated by the compositor if it decides to. Clients have no
way to prevent the compositor from potentially decorating them, if they
don't want any decorations they should destroy the
xdg_toplevel_decoration object.
Some toolkits allow toggling toplevel decorations at runtime. In this
case they need a way to transition from having no decorations at all to
a state where they can be decorated.
Allow creating an xdg_toplevel_decoration object on an already-mapped
toplevel to accomodate for this use-case.

The interface description says the target_primaries event is mandatory,
but event documentation disagreed. Fix the disagreement by requiring the
event always.
This saves the compositor from figuring out whether to send the event or
not. I do not know what compositors do today, but sending the event is
definitely safe. Compositors that do not always send the event are
retroactively deemed buggy.

Note that wp_image_description_v1 is not a frozen interface. Therefore
it must always be a descendant of wp_color_manager_v1.
In order to allow other protocols, such as ext-image-capture-source-v1,
to define the equivalent of
wp_color_management_output_v1.get_image_description, we must therefore
create an indirection between the new protocol and
wp_image_description_v1 that is resolved through wp_color_manager_v1
itself.
This is a prerequisite for adding color management support to the
ext-image-copy-capture-v1 protocol.

ICC-based calibrated print workflows have generally used the sRGB
two-piece transfer characteristic. The CRT era monitors were exclusively
power curve, but print workflows used software calibration to meet the
two-piece curve. Everyone else used the monitor native transfer
characteristic.
Acknowledge that both ways exist, and allow describing both as what they
are.
Mesa is already using "srgb" if it is available, for programs that
actually expect gamma22. Exposing "srgb" with its literal definition
would make a compositor (KWin has been named) appear regressing in
picture quality. The same with "ext_srgb" as Mesa used to map
VK_COLOR_SPACE_EXTENDED_SRGB_NONLINEAR_EXT to it, probably incorrectly.
sRGB is specified to use a power-law 2.2 display, and reality is not
consistent. Some compositors take srgb to mean gamma22 already, so there
is practical ambiguity. There are also endless discussions about which
one sRGB actually is and when: power-law 2.2 or the piece-wise function.
Monitors are manufactured both ways and they are often even switchable
between the two. Therefore deprecate the "srgb" value, it is too easy to
pick and assume one behavior while someone else assumes the other
behavior.
Additionally, extending the range beyond 1.0 would significantly diverge
between srgb and gamma22 because of the different exponent. Assuming
that ext_srgb is identical to srgb for [0.0, 1.0] would conflict with a
compositor that takes srgb as gamma22 but implements ext_srgb by the
piece-wise function.
Given that monitors with the piece-wise function exist or are calibrated
to it, and materials are prepared on them, add a new value explicitly
for the sRGB piece-wise function. Its name deliberately does not include
"srgb".

A 32-bit image description identity number could theoretically wrap
around in 1.4 years if a new one is allocated 100 times per second.
Compositors that avoid 32-bit wrap-around are allowed to aggressively
recycle numbers, which poses a requirement on clients to hold on to the
image description object in order to keep its number live. Clients might
not do so regardless of documentation, and on compositors that recycle
only after wrap-around clients would not see any problems. This could
cause strange issues in clients on former kind of compositors.
In order to avoid all that, introduce a new 64-bit image description
identity number which has no fear of wrap-around, and require such
numbers to be never recycled. This makes the compositor number allocator
trivial, and clients are more likely to handle it correctly by accident.

ANSI/CTA-861-H does not require that maxCLL or maxFALL be within the
Mastering Display Luminance range, and it is common for movies to have a
maxCLL greater than the Mastering Display Luminance. Additionally,
Microsoft's own documentation* contains an example that does not pass
the restriction in the protocol. These values are valid, used in the
real world, and clients should not need to discard them. We keep the
requirement that maxFALL <= maxCLL since that is required, but these
values have no relation to the Mastering Display Luminance.
See #263 for further details on why the restriction on maxCLL and
maxFALL is not desirable. Fixes#263.

In an attempt to specify clipping behavior[1] it was found that it would
lead to predictable behavior turning into undefined behavior when a
compositor gains support for extended_color_volume. That would be
awkward.
Instead of specifying clipping to the primary color volume bounds (which
may then disappear), let's leave it undefined, and emphasize the
undefined-ness of exceeding the target color volume instead.
