+ * The following are required from clients:

+ * - Clients must ensure that either all data in the dma-buf is
+ * coherent for all subsequent read access or that coherency is
+ * correctly handled by the underlying kernel-side dma-buf
+ * implementation.
+ *
+ * - Don't make any more attachments after sending the buffer to the

+ * the compositor not being able to use (re-import) an existing
+ * dmabuf-based wl_buffer.
+ *
+ * The underlying graphics stack must ensure the following:
+ *
+ * - The dmabuf file descriptors relayed to the server will stay valid
+ * for the whole lifetime of the wl_buffer. This means the server may
+ * at any time use those fds to import the dmabuf into any kernel
+ * sub-system that might accept it.
+ *
+ * To create a wl_buffer from one or more dmabufs, a client creates a
+ * zwp_linux_dmabuf_params_v1 object with a zwp_linux_dmabuf_v1.create_params
+ * request. All planes required by the intended format are added with
+ * the 'add' request. Finally, a 'create' or 'create_immed' request is
+ * issued, which has the following outcome depending on the import success.
+ *
+ * The 'create' request,
+ * - on success, triggers a 'created' event which provides the final
+ * wl_buffer to the client.
+ * - on failure, triggers a 'failed' event to convey that the server
+ * cannot use the dmabufs received from the client.
+ *
+ * For the 'create_immed' request,
+ * - on success, the server immediately imports the added dmabufs to
+ * create a wl_buffer. No event is sent from the server in this case.
+ * - on failure, the server can choose to either:
+ * - terminate the client by raising a fatal error.
+ * - mark the wl_buffer as failed, and send a 'failed' event to the
+ * client. If the client uses a failed wl_buffer as an argument to any
+ * request, the behaviour is compositor implementation-defined.
+ *
+ * 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.

+ * authoritative source on how the format codes should work.
+ *
+ * The 'flags' is a bitfield of the flags defined in enum "flags".
+ * 'y_invert' means the that the image needs to be y-flipped.
+ *
+ * Flag 'interlaced' means that the frame in the buffer is not
+ * progressive as usual, but interlaced. An interlaced buffer as
+ * supported here must always contain both top and bottom fields.
+ * The top field always begins on the first pixel row. The temporal
+ * ordering between the two fields is top field first, unless

+ * This protocol does not convey any information about field rate,
+ * duration, or timing, other than the relative ordering between the

+ * attached, applying the wl_surface state, wl_surface.frame callback
+ * trigger, presentation, or any other point in the compositor cycle
+ * is used to measure the frame or field times. There is no support
+ * for detecting missed or late frames/fields/buffers either, and
+ * there is no support whatsoever for cooperating with interlaced
+ * compositor output.
+ *
+ * The composited image quality resulting from the use of interlaced
+ * buffers is explicitly undefined. A compositor may use elaborate
+ * hardware features or software to deinterlace and create progressive
+ * output frames from a sequence of interlaced input buffers, or it
+ * may produce substandard image quality. However, compositors that
+ * cannot guarantee reasonable image quality in all cases are recommended
+ * to just reject all interlaced buffers.

+ * mismatch between the number of planes and the format, bad
+ * format, bad offset or stride, may be indicated by fatal protocol
+ * errors: INCOMPLETE, INVALID_FORMAT, INVALID_DIMENSIONS,
+ * OUT_OF_BOUNDS.
+ *

+ * bugs are returned via the 'failed' event as non-fatal. This

+ * if it fails.

+ * @page page_pointer_constraints_unstable_v1 The
+ * pointer_constraints_unstable_v1 protocol protocol for constraining pointer
+ * motions
+ *
+ * @section page_desc_pointer_constraints_unstable_v1 Description
+ *
+ * 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
+ * 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.
+ *
+ * @section page_ifaces_pointer_constraints_unstable_v1 Interfaces
+ * - @subpage page_iface_zwp_pointer_constraints_v1 - constrain the movement of
+ * a pointer
+ * - @subpage page_iface_zwp_locked_pointer_v1 - receive relative pointer motion

+ * There may not be another pointer constraint of any kind requested or

+ * 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

+ * @page page_relative_pointer_unstable_v1 The relative_pointer_unstable_v1
+ * protocol protocol for relative pointer motion events
+ *
+ * @section page_desc_relative_pointer_unstable_v1 Description
+ *
+ * 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.

+ *
+ * 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.
+ *
+ * The x, y arguments of wl_surface.attach are applied as normal to
+ * the surface. They indicate how many pixels to remove from the
+ * surface size from the left and the top. In other words, they are
+ * still in the surface-local coordinate system, just like dst_width
+ * and dst_height are.
+ *
+ * If the wl_surface associated with the wp_viewport is destroyed,
+ * all wp_viewport requests except 'destroy' raise the protocol error
+ * no_surface.

+ * @page page_xdg_activation_v1 The xdg_activation_v1 protocol
+ * Protocol for requesting activation of surfaces
+ *
+ * @section page_desc_xdg_activation_v1 Description
+ *
+ * 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
+ * XDG_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.

+ * @page page_xdg_output_unstable_v1 The xdg_output_unstable_v1 protocol
+ * Protocol to describe output regions
+ *
+ * @section page_desc_xdg_output_unstable_v1 Description
+ *
+ * This protocol aims at describing outputs in a way which is more in line
+ * with the concept of an output on desktop oriented systems.
+ *
+ * Some information are more specific to the concept of an output for
+ * a desktop oriented system and may not make sense in other applications,
+ * such as IVI systems for example.
+ *
+ * Typically, the global compositor space on a desktop system is made of
+ * a contiguous or overlapping set of rectangular regions.
+ *
+ * Some of the information provided in this protocol might be identical
+ * to their counterparts already available from wl_output, in which case
+ * the information provided by this protocol should be preferred to their
+ * equivalent in wl_output. The goal is to move the desktop specific
+ * concepts (such as output location within the global compositor space,
+ * the connector name and types, etc.) out of the core wl_output protocol.
+ *
+ * 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.

+   *
+   * For example, a surface without any buffer scale, transformation
+   * nor rotation set, with the size matching the logical_size will
+   * have the same size as the corresponding output when displayed.
+   *
+   * Most regular Wayland clients should not pay attention to the

+   * Some clients such as Xwayland, however, need this to configure
+   * their surfaces in the global compositor space as the compositor
+   * may apply a different scale from what is advertised by the
+   * output scaling property (to achieve fractional scaling, for
+   * example).
+   *
+   * For example, for a wl_output mode 3840×2160 and a scale factor
+   * 2:
+   *
+   * - A compositor not scaling the surface buffers will advertise a
+   * logical size of 3840×2160,
+   *
+   * - A compositor automatically scaling the surface buffers will
+   * advertise a logical size of 1920×1080,
+   *
+   * - A compositor using a fractional scale of 1.5 will advertise a
+   * logical size to 2560×1620.
+   *
+   * For example, for a wl_output mode 1920×1080 and a 90 degree
+   * rotation, the compositor will advertise a logical size of
+   * 1080x1920.
+   *
+   * The logical_size event is sent after creating an xdg_output (see
+   * xdg_output_manager.get_xdg_output) and whenever the logical size
+   * of the output changes, either as a result of a change in the
+   * applied scale or because of a change in the corresponding output
