<description summary="Protocol for requesting fractional surface scales">
This protocol allows a compositor to suggest for surfaces to render at
fractional scales.
A client can submit scaled content by utilizing wp_viewport. This is done by
creating a wp_viewport object for the surface and setting the destination
rectangle to the surface size before the scale factor is applied.
The buffer size is calculated by multiplying the surface size by the
intended scale.
The wl_surface buffer scale should remain set to 1.
If a surface has a surface-local size of 100 px by 50 px and wishes to
submit buffers with a scale of 1.5, then a buffer of 150px by 75 px should
be used and the wp_viewport destination rectangle should be 100 px by 50 px.
For toplevel surfaces, the size is rounded halfway away from zero. The
rounding algorithm for subsurface position and size is not defined.

<description summary="protocol for constraining pointer motions">
This protocol specifies a set of interfaces used for adding constraints to
the motion of a pointer. Possible constraints include confining pointer
motions to a given region, or locking it to its current position.
In order to constrain the pointer, a client must first bind the global
interface "wp_pointer_constraints" which, if a compositor supports pointer
constraints, is exposed by the registry. Using the bound global object, the
client uses the request that corresponds to the type of constraint it wants
to make. See wp_pointer_constraints for more details.
Warning! The protocol described in this file is experimental and backward
incompatible changes may be made. Backward compatible changes may be added
together with the corresponding interface version bump. Backward
incompatible changes are done by bumping the version number in the protocol

<interface name="zwp_pointer_constraints_v1" version="1">
<description summary="constrain the movement of a pointer">
The global interface exposing pointer constraining functionality. It
exposes two requests: lock_pointer for locking the pointer to its
position, and confine_pointer for locking the pointer to a region.
The lock_pointer and confine_pointer requests create the objects
wp_locked_pointer and wp_confined_pointer respectively, and the client can
use these objects to interact with the lock.
For any surface, only one lock or confinement may be active across all
wl_pointer objects of the same seat. If a lock or confinement is requested
when another lock or confinement is active or requested on the same surface
and with any of the wl_pointer objects of the same seat, an
'already_constrained' error will be raised.

<request name="lock_pointer">
<description summary="lock pointer to a position">
The lock_pointer request lets the client request to disable movements of
the virtual pointer (i.e. the cursor), effectively locking the pointer
to a position. This request may not take effect immediately; in the
future, when the compositor deems implementation-specific constraints
are satisfied, the pointer lock will be activated and the compositor
sends a locked event.
The protocol provides no guarantee that the constraints are ever
satisfied, and does not require the compositor to send an error if the
constraints cannot ever be satisfied. It is thus possible to request a
lock that will never activate.
There may not be another pointer constraint of any kind requested or
active on the surface for any of the wl_pointer objects of the seat of
the passed pointer when requesting a lock. If there is, an error will be
raised. See general pointer lock documentation for more details.
The intersection of the region passed with this request and the input
region of the surface is used to determine where the pointer must be
in order for the lock to activate. It is up to the compositor whether to
warp the pointer or require some kind of user interaction for the lock
to activate. If the region is null the surface input region is used.
A surface may receive pointer focus without the lock being activated.
The request creates a new object wp_locked_pointer which is used to
interact with the lock as well as receive updates about its state. See
the the description of wp_locked_pointer for further information.
Note that while a pointer is locked, the wl_pointer objects of the
corresponding seat will not emit any wl_pointer.motion events, but
relative motion events will still be emitted via wp_relative_pointer
objects of the same seat. wl_pointer.axis and wl_pointer.button events
are unaffected.

<description summary="protocol for relative pointer motion events">
This protocol specifies a set of interfaces used for making clients able to
receive relative pointer events not obstructed by barriers (such as the
monitor edge or other pointer barriers).
To start receiving relative pointer events, a client must first bind the
global interface "wp_relative_pointer_manager" which, if a compositor
supports relative pointer motion events, is exposed by the registry. After
having created the relative pointer manager proxy object, the client uses
it to create the actual relative pointer object using the
"get_relative_pointer" request given a wl_pointer. The relative pointer
motion events will then, when applicable, be transmitted via the proxy of
the newly created relative pointer object. See the documentation of the
relative pointer interface for more details.
Warning! The protocol described in this file is experimental and backward
incompatible changes may be made. Backward compatible changes may be added
together with the corresponding interface version bump. Backward
incompatible changes are done by bumping the version number in the protocol
and interface names and resetting the interface version. Once the protocol
is to be declared stable, the 'z' prefix and the version number in the
protocol and interface names are removed and the interface version number is
reset.

Relative x/y pointer motion from the pointer of the seat associated with

A relative motion is in the same dimension as regular wl_pointer motion
events, except they do not represent an absolute position. For example,
moving a pointer from (x, y) to (x', y') would have the equivalent
relative motion (x' - x, y' - y). If a pointer motion caused the
absolute pointer position to be clipped by for example the edge of the
monitor, the relative motion is unaffected by the clipping and will
represent the unclipped motion.
This event also contains non-accelerated motion deltas. The
non-accelerated delta is, when applicable, the regular pointer motion
delta as it was before having applied motion acceleration and other
transformations such as normalization.
Note that the non-accelerated delta does not represent 'raw' events as
they were read from some device. Pointer motion acceleration is device-
and configuration-specific and non-accelerated deltas and accelerated
deltas may have the same value on some devices.
Relative motions are not coupled to wl_pointer.motion events, and can be
sent in combination with such events, but also independently. There may
also be scenarios where wl_pointer.motion is sent, but there is no
relative motion. The order of an absolute and relative motion event
originating from the same physical motion is not guaranteed.
If the client needs button events or focus state, it can receive them
from a wl_pointer object of the same seat that the wp_relative_pointer
object is associated with.

<description summary="crop and scale interface to a wl_surface">
An additional interface to a wl_surface object, which allows the
client to specify the cropping and scaling of the surface
contents.
This interface works with two concepts: the source rectangle (src_x,
src_y, src_width, src_height), and the destination size (dst_width,
dst_height). The contents of the source rectangle are scaled to the
destination size, and content outside the source rectangle is ignored.
This state is double-buffered, and is applied on the next
wl_surface.commit.
The two parts of crop and scale state are independent: the source
rectangle, and the destination size. Initially both are unset, that
is, no scaling is applied. The whole of the current wl_buffer is
used as the source, and the surface size is as defined in
wl_surface.attach.
If the destination size is set, it causes the surface size to become
dst_width, dst_height. The source (rectangle) is scaled to exactly
this size. This overrides whatever the attached wl_buffer size is,
unless the wl_buffer is NULL. If the wl_buffer is NULL, the surface
has no content and therefore no size. Otherwise, the size is always
at least 1x1 in surface local coordinates.
If the source rectangle is set, it defines what area of the wl_buffer is
taken as the source. If the source rectangle is set and the destination
size is not set, then src_width and src_height must be integers, and the
surface size becomes the source rectangle size. This results in cropping
without scaling. If src_width or src_height are not integers and
destination size is not set, the bad_size protocol error is raised when
the surface state is applied.
The coordinate transformations from buffer pixel coordinates up to
the surface-local coordinates happen in the following order:
1. buffer_transform (wl_surface.set_buffer_transform)
2. buffer_scale (wl_surface.set_buffer_scale)
3. crop and scale (wp_viewport.set*)
This means, that the source rectangle coordinates of crop and scale
are given in the coordinates after the buffer transform and scale,
i.e. in the coordinates that would be the surface-local coordinates
if the crop and scale was not applied.
If src_x or src_y are negative, the bad_value protocol error is raised.
Otherwise, if the source rectangle is partially or completely outside of
the non-NULL wl_buffer, then the out_of_buffer protocol error is raised
when the surface state is applied. A NULL wl_buffer does not raise the
out_of_buffer error.
If the wl_surface associated with the wp_viewport is destroyed,
all wp_viewport requests except 'destroy' raise the protocol error
no_surface.
If the wp_viewport object is destroyed, the crop and scale
state is removed from the wl_surface. The change will be applied
on the next wl_surface.commit.

<description summary="Protocol for requesting activation of surfaces">
The way for a client to pass focus to another toplevel is as follows.
The client that intends to activate another toplevel uses the
xdg_activation_v1.get_activation_token request to get an activation token.
This token is then forwarded to the client, which is supposed to activate
one of its surfaces, through a separate band of communication.
One established way of doing this is through the XDG_ACTIVATION_TOKEN
environment variable of a newly launched child process. The child process
should unset the environment variable again right after reading it out in
order to avoid propagating it to other child processes.
Another established way exists for Applications implementing the D-Bus
interface org.freedesktop.Application, which should get their token under
activation-token on their platform_data.
In general activation tokens may be transferred across clients through
means not described in this protocol.
The client to be activated will then pass the token
it received to the xdg_activation_v1.activate request. The compositor can
then use this token to decide how to react to the activation request.
The token the activating client gets may be ineffective either already at
the time it receives it, for example if it was not focused, for focus
stealing prevention. The activating client will have no way to discover
the validity of the token, and may still forward it to the to be activated
client.
The created activation token may optionally get information attached to it
that can be used by the compositor to identify the application that we
intend to activate. This can for example be used to display a visual hint
about what application is being started.
Warning! The protocol described in this file is currently in the testing
phase. Backward compatible changes may be added together with the
corresponding interface version bump. Backward incompatible changes can
only be done by creating a new major version of the extension.

<interface name="zxdg_decoration_manager_v1" version="1">
<description summary="window decoration manager">
This interface allows a compositor to announce support for server-side
decorations.
A window decoration is a set of window controls as deemed appropriate by
the party managing them, such as user interface components used to move,
resize and change a window's state.
A client can use this protocol to request being decorated by a supporting
compositor.
If compositor and client do not negotiate the use of a server-side
decoration using this protocol, clients continue to self-decorate as they
see fit.
Warning! The protocol described in this file is experimental and
backward incompatible changes may be made. Backward compatible changes
may be added together with the corresponding interface version bump.
Backward incompatible changes are done by bumping the version number in
the protocol and interface names and resetting the interface version.
Once the protocol is to be declared stable, the 'z' prefix and the
version number in the protocol and interface names are removed and the
interface version number is reset.

The compositor can decide not to use the client's mode and enforce a
