2617 * is used in major toolkits (and the behavior recommended for
2618 * compositors) is:
2619 *
2620 * - If no modifiers are pressed, the first match (in bit order)
2621 * will be used.
2622 * - Pressing Shift selects "move", if enabled in the mask.
2623 * - Pressing Control selects "copy", if enabled in the mask.
2624 *
2625 * Behavior beyond that is considered implementation-dependent.
2626 * Compositors may for example bind other modifiers (like Alt/Meta)
2627 * or drags initiated with other buttons than BTN_LEFT to specific
2628 * actions (e.g. "ask").

3718 * This request is used to describe the regions where the pending
3719 * buffer is different from the current surface contents, and where
3720 * the surface therefore needs to be repainted. The compositor
3721 * ignores the parts of the damage that fall outside of the surface.
3722 *
3723 * Damage is double-buffered state, see wl_surface.commit.
3724 *
3725 * The damage rectangle is specified in buffer coordinates,
3726 * where x and y specify the upper left corner of the damage rectangle.
3727 *
3728 * The initial value for pending damage is empty: no damage.
3729 * wl_surface.damage_buffer adds pending damage: the new pending
3730 * damage is the union of old pending damage and the given rectangle.
3731 *
3732 * wl_surface.commit assigns pending damage as the current damage,
3733 * and clears pending damage. The server will clear the current
3734 * damage as it repaints the surface.
3735 *
3736 * This request differs from wl_surface.damage in only one way - it
3737 * takes damage in buffer coordinates instead of surface-local
3738 * coordinates. While this generally is more intuitive than surface
3739 * coordinates, it is especially desirable when using wp_viewport
3740 * or when a drawing library (like EGL) is unaware of buffer scale
3741 * and buffer transform.
3742 *
3743 * Note: Because buffer transformation changes and damage requests may
3744 * be interleaved in the protocol stream, it is impossible to determine
3745 * the actual mapping between surface and buffer damage until
3746 * wl_surface.commit time. Therefore, compositors wishing to take both
3747 * kinds of damage into account will have to accumulate damage from the
3748 * two requests separately and only transform from one to the other
3749 * after receiving the wl_surface.commit.

4216 * A wl_pointer.frame event is sent for every logical event group,

4220 *
4221 * The wl_pointer.enter and wl_pointer.leave events are logical
4222 * events generated by the compositor and not the hardware. These
4223 * events are also grouped by a wl_pointer.frame. When a pointer
