3714 * This request is used to describe the regions where the pending
3715 * buffer is different from the current surface contents, and where
3716 * the surface therefore needs to be repainted. The compositor
3717 * ignores the parts of the damage that fall outside of the surface.
3718 *
3719 * Damage is double-buffered state, see wl_surface.commit.
3720 *
3721 * The damage rectangle is specified in buffer coordinates,
3722 * where x and y specify the upper left corner of the damage rectangle.
3723 *
3724 * The initial value for pending damage is empty: no damage.
3725 * wl_surface.damage_buffer adds pending damage: the new pending
3726 * damage is the union of old pending damage and the given rectangle.
3727 *
3728 * wl_surface.commit assigns pending damage as the current damage,
3729 * and clears pending damage. The server will clear the current
3730 * damage as it repaints the surface.
3731 *
3732 * This request differs from wl_surface.damage in only one way - it
3733 * takes damage in buffer coordinates instead of surface-local
3734 * coordinates. While this generally is more intuitive than surface
3735 * coordinates, it is especially desirable when using wp_viewport
3736 * or when a drawing library (like EGL) is unaware of buffer scale
3737 * and buffer transform.
3738 *
3739 * Note: Because buffer transformation changes and damage requests may
3740 * be interleaved in the protocol stream, it is impossible to determine
3741 * the actual mapping between surface and buffer damage until
3742 * wl_surface.commit time. Therefore, compositors wishing to take both
3743 * kinds of damage into account will have to accumulate damage from the
3744 * two requests separately and only transform from one to the other
3745 * after receiving the wl_surface.commit.

4211 *
4212 * A wl_pointer.frame event is sent for every logical event group,

4214 * Specifically, a client may get a sequence: motion, frame,
4215 * button, frame, axis, frame, axis_stop, frame.
4216 *
4217 * The wl_pointer.enter and wl_pointer.leave events are logical
4218 * events generated by the compositor and not the hardware. These
4219 * events are also grouped by a wl_pointer.frame. When a pointer
