/**
 * @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.

  /**
   * size of the output in the global compositor space
   *
   * The logical_size event describes the size of the output in the
   * global compositor space.
   *
   * 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
   * logical size and would rather rely on xdg_shell interfaces.
   *
   * 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
   * mode(see wl_output.mode) or transform (see wl_output.transform).

   * similar behaviors.
   *

   * among all wl_output globals, but if a wl_output global is
   * destroyed the same name may be reused later. The names will also
   * remain consistent across sessions with the same hardware and
   * software configuration.
   *
   * Examples of names include 'HDMI-A-1', 'WL-1', 'X11-1', etc.
   * However, do not assume that the name is a reflection of an
   * underlying DRM connector, X11 connection, etc.
   *
   * The name event is sent after creating an xdg_output (see
