+ * @page page_gtk_primary_selection The gtk_primary_selection protocol
+ * Primary selection protocol
+ *
+ * @section page_desc_gtk_primary_selection Description
+ *
+ * This protocol provides the ability to have a primary selection device to
+ * match that of the X server. This primary selection is a shortcut to the
+ * common clipboard selection, where text just needs to be selected in order
+ * to allow copying it elsewhere. The de facto way to perform this action
+ * is the middle mouse button, although it is not limited to this one.
+ *
+ * Clients wishing to honor primary selection should create a primary
+ * selection source and set it as the selection through
+ * wp_primary_selection_device.set_selection whenever the text selection
+ * changes. In order to minimize calls in pointer-driven text selection,
+ * it should happen only once after the operation finished. Similarly,
+ * a NULL source should be set when text is unselected.
+ *
+ * wp_primary_selection_offer objects are first announced through the
+ * wp_primary_selection_device.data_offer event. Immediately after this event,
+ * the primary data offer will emit wp_primary_selection_offer.offer events
+ * to let know of the mime types being offered.
+ *
+ * When the primary selection changes, the client with the keyboard focus
+ * will receive wp_primary_selection_device.selection events. Only the client
+ * with the keyboard focus will receive such events with a non-NULL
+ * wp_primary_selection_offer. Across keyboard focus changes, previously
+ * focused clients will receive wp_primary_selection_device.events with a
+ * NULL wp_primary_selection_offer.
+ *
+ * In order to request the primary selection data, the client must pass
+ * a recent serial pertaining to the press event that is triggering the
+ * operation, if the compositor deems the serial valid and recent, the
+ * wp_primary_selection_source.send event will happen in the other end
+ * to let the transfer begin. The client owning the primary selection
+ * should write the requested data, and close the file descriptor
+ * immediately.
+ *
+ * If the primary selection owner client disappeared during the transfer,
+ * the client reading the data will receive a
+ * wp_primary_selection_device.selection event with a NULL
+ * wp_primary_selection_offer, the client should take this as a hint
+ * to finish the reads related to the no longer existing offer.
+ *
+ * The primary selection owner should be checking for errors during
+ * writes, merely cancelling the ongoing transfer if any happened.

+ * @page page_iface_zwp_linux_dmabuf_v1 zwp_linux_dmabuf_v1
+ * @section page_iface_zwp_linux_dmabuf_v1_desc Description
+ *
+ * Following the interfaces from:
+ * https://www.khronos.org/registry/egl/extensions/EXT/EGL_EXT_image_dma_buf_import.txt
+ * and the Linux DRM sub-system's AddFb2 ioctl.
+ *
+ * This interface offers ways to create generic dmabuf-based
+ * wl_buffers. Immediately after a client binds to this interface,
+ * the set of supported formats and format modifiers is sent with
+ * 'format' and 'modifier' events.
+ *
+ * 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
+ * compositor. Making more attachments later increases the risk of
+ * 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.

+/**
+ * @defgroup iface_zwp_linux_dmabuf_v1 The zwp_linux_dmabuf_v1 interface
+ *
+ * Following the interfaces from:
+ * https://www.khronos.org/registry/egl/extensions/EXT/EGL_EXT_image_dma_buf_import.txt
+ * and the Linux DRM sub-system's AddFb2 ioctl.
+ *
+ * This interface offers ways to create generic dmabuf-based
+ * wl_buffers. Immediately after a client binds to this interface,
+ * the set of supported formats and format modifiers is sent with
+ * 'format' and 'modifier' events.
+ *
+ * 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
+ * compositor. Making more attachments later increases the risk of
+ * 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.

+ * @page page_wp_primary_selection_unstable_v1 The wp_primary_selection_unstable_v1 protocol
+ * Primary selection protocol
+ *
+ * @section page_desc_wp_primary_selection_unstable_v1 Description
+ *
+ * This protocol provides the ability to have a primary selection device to
+ * match that of the X server. This primary selection is a shortcut to the
+ * common clipboard selection, where text just needs to be selected in order
+ * to allow copying it elsewhere. The de facto way to perform this action
+ * is the middle mouse button, although it is not limited to this one.
+ *
+ * Clients wishing to honor primary selection should create a primary
+ * selection source and set it as the selection through
+ * wp_primary_selection_device.set_selection whenever the text selection
+ * changes. In order to minimize calls in pointer-driven text selection,
+ * it should happen only once after the operation finished. Similarly,
+ * a NULL source should be set when text is unselected.
+ *
+ * wp_primary_selection_offer objects are first announced through the
+ * wp_primary_selection_device.data_offer event. Immediately after this event,
+ * the primary data offer will emit wp_primary_selection_offer.offer events
+ * to let know of the mime types being offered.
+ *
+ * When the primary selection changes, the client with the keyboard focus
+ * will receive wp_primary_selection_device.selection events. Only the client
+ * with the keyboard focus will receive such events with a non-NULL
+ * wp_primary_selection_offer. Across keyboard focus changes, previously
+ * focused clients will receive wp_primary_selection_device.events with a
+ * NULL wp_primary_selection_offer.
+ *
+ * In order to request the primary selection data, the client must pass
+ * a recent serial pertaining to the press event that is triggering the
+ * operation, if the compositor deems the serial valid and recent, the
+ * wp_primary_selection_source.send event will happen in the other end
+ * to let the transfer begin. The client owning the primary selection
+ * should write the requested data, and close the file descriptor
+ * immediately.
+ *
+ * If the primary selection owner client disappeared during the transfer,
+ * the client reading the data will receive a
+ * wp_primary_selection_device.selection event with a NULL
+ * wp_primary_selection_offer, the client should take this as a hint
+ * to finish the reads related to the no longer existing offer.
+ *
+ * The primary selection owner should be checking for errors during
+ * writes, merely cancelling the ongoing transfer if any happened.

+ * @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.

+   *
+   * 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
