 *
 * 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.
 * 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.

 * buffers. The wl_buffer is not created immediately but returned via
 * the 'created' event if the dmabuf sharing succeeds. The sharing
 * may fail at runtime for reasons a client cannot predict, in
 * which case the 'failed' event is triggered.
 *
 * The 'format' argument is a DRM_FORMAT code, as defined by the
 * libdrm's drm_fourcc.h. The Linux kernel's DRM sub-system is the
 * 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
 * 'bottom_first' is specified. It is undefined whether 'bottom_first'
 * is ignored if 'interlaced' is not set.
 *
 * This protocol does not convey any information about field rate,
 * duration, or timing, other than the relative ordering between the
 * two fields in one buffer. A compositor may have to estimate the
 * intended field rate from the incoming buffer rate. It is undefined
 * whether the time of receiving wl_surface.commit with a new buffer
 * 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.
 *
 * Any argument errors, including non-positive width or height,
 * 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.
 *
 * Dmabuf import errors in the server that are not obvious client
 * bugs are returned via the 'failed' event as non-fatal. This
 * allows attempting dmabuf sharing and falling back in the client
 * if it fails.
 *
 * This request can be sent only once in the object's lifetime, after
 * which the only legal request is destroy. This object should be
 * destroyed after issuing a 'create' request. Attempting to use this
 * object after issuing 'create' raises ALREADY_USED protocol error.
