 * in, e.g. the only popup you are allowed to destroy at all times is the
 * topmost one.

 * nested grabbing popup as well. When a compositor dismisses popups, it
 * will follow the same dismissing order as required from the client.
 *
 * If the topmost grabbing popup is destroyed, the grab will be returned to
 * the parent of the popup, if that parent previously had an explicit grab.
 *
 * If the parent is a grabbing popup which has already been dismissed, this
 * popup will be immediately dismissed. If the parent is a popup that did
 * not take an explicit grab, an error will be raised.
 *
 * During a popup grab, the client owning the grab will receive pointer
 * and touch events for all their surfaces as normal (similar to an
 * "owner-events" grab in X11 parlance), while the top most grabbing popup
 * will always have keyboard focus.
