This commit introduces an experimental text-input protocol as a functionally exact copy of text-input-v3.
The goal of this is to arrive at an improved text-input-next protocol, without committing to backwards-compatible changes beforehand.

It is not possible to write equations nicely in the XML, so we need an
appendix.
First, the appendix explicitly defines the transfer functions that the
protocol enumeration refers to. Leaving them to be inferred from the
ITU-R and other specifications was too confusing.

References to H.273 are confusing people:
https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requests/442#note_3079717
The confusion arises from H.273 usually referring to encoding standards
which only indirectly define a reference display. Wayland
color-management is only interested in the displays.

The BT.1886 recommendation is impossible to implement precisely if
min_lum includes other sources than the display emission. BT.1886
transfer function requires L_W and L_B to determine the function
parameters black level lift and gain. The black level lift changes the
non-linearity, and cannot be implemented as an optical addition.
I believe the inclusion of optical additives, particularly the ambient
flare, came from sRGB specification. I do not recall seeing it anywhere
else.
Drop the optical additives from the definitions of the luminances. It
was probably incorrect for everything but sRGB, if they even had it
specified at all. This allows implementing BT.1886 as specified.

There should only be decoration outside of it, no functional UI elements. This
is especially important on some compositors that clip windows to their window
geometry in some situations (like when it's in a tile).

The original MR did not copy the popup interface because it's been limited and inadequate for actual use.
This introduces a version heavily based on xdg-popup.

The value was zero because the enum was not a bitfield at some point when the protocol was
developed and I forgot to change the value to one when making it a bitfield.
This is technically a breaking change, but as the client could never receive the blur
capability before this commit, it won't actually break anything - it was already broken.

I found it unfortunate that we left in a TF code that will intuitively
be used incorrectly. It is as if we designed the protocol so that
compositors will need to fix up client image descriptions.
I am not aware of any use case that would want to target a display with
the sRGB piece-wise transfer function, that would be a non-standard
display.
This patch does not help compositors avoid needing to second-guess
client image descriptions using srgb TF, but it at least documents the
situation. We could choose to out-law srgb TF in a minor version bump,
or drop it completely in the next major version. Compositors can also
not advertise support for srgb TF.

This protocol allows the client to specify a region behind the surface that should
be blurred, with the intention to improve the visuals of for example panels or
terminals.
This protocol is roughly based on the org_kde_kwin_blur protocol, which has been
in use since 2015. The protocol is made more generically though, so that other
related effects can be added in the future, like for example contrast improvements.

This change strips down the protocol to functionality that corresponds
to text-input-v3, is already useful, typically implemented in the wild
(squeekboard), and well-understood.
Dificult to implement well functionality like keyboard grabs is removed
to find a better solution without stopping the development of the basic
functionality.

This commit introduces an experimental input-method protocol as an exact
copy of the fle describing the unofficial zwp_input_method_v2 from
squeekboard.
It's also supported by wlroots and smithay.
This protocol is the counterpart to text-input-v3. It gives the
compositor a standard way to outsource the handling of the input method.

This new protocol aims to let clients define the remaining bits of the color
encoding they are using in their buffers.
In particular, this lets clients define the how the alpha has been encoded and
how conversions from YCbCr to RGB take place.

The window id protocol allows clients to set a tag for toplevels, which
the compositor can use to identify them even after the application
has been restarted. This persistent identification can be used by the
compositor to restore properties like position, size, "always on top",
and it can also be used for allowing users to create rules that change
compositor behavior for specific windows.

An edge constraint is an complementery state to the tiled state, meaning
that it's not only tiled, but constrained in a way that it can't resize
in that direction.
This typically means that the constrained edge is tiled against a
monitor edge. An example configuration is two windows tiled next to each
other on a single monitor. Together they cover the whole work area.
The left window would have the following tiled and edge constraint
state:
[ tiled_top, tiled_right, tiled_bottom, tiled_left,
constrained_top, constrained_bottom, constrained_left ]
while the right window would have the following:
[ tiled_top, tiled_right, tiled_bottom, tiled_left,
constrained_top, constrained_bottom, constrained_right ]
This aims to replace and deprecate the `gtk_surface1.configure_edges`
event and the `gtk_surface1.edge_constraint` enum.

Some tablets provide one or more rotary controls (see e.g. the Huion
Inspiroy Dial 2) that provide delta information effectively equivalent
to a mouse wheel. Expose those in the same way as the strip or ring
controls, with the event matching the wl_pointer.axis_v120 approach.
Like a typical mouse wheel we do not expect there to be a source
information, so this is left out of the interface.

The move cursor is ambiguous, since it is used in two context:
for DND, and for resizing. This commit adds a separate enum

This is the cursor shape that corresponds to the ASK drag action
in the core protocol. The expected semantics of ASK are that the
drop target presents the user with a choice of actions when the
drop happens. A typical image for this cursor is a default cursor
