+ *
+ * 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

+ * 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.

+ * It is not mandatory to issue 'create'. If a client wants to
+ * cancel the buffer creation, it can just destroy this object.
