+ * This request makes the created popup take an explicit grab. An explicit
+ * grab will be dismissed when the user dismisses the popup, or when the
+ * client destroys the xdg_popup. This can be done by the user clicking
+ * outside the surface, using the keyboard, or even locking the screen
+ * through closing the lid or a timeout.
+ *
+ * If the compositor denies the grab, the popup will be immediately
+ * dismissed.
+ *
+ * This request must be used in response to some sort of user action like a
+ * button press, key press, or touch down event. The serial number of the
+ * event should be passed as 'serial'.
+ *
+ * The parent of a grabbing popup must either be an xdg_toplevel surface or
+ * another xdg_popup with an explicit grab. If the parent is another
+ * xdg_popup it means that the popups are nested, with this popup now being
+ * the topmost popup.
+ *
+ * Nested popups must be destroyed in the reverse order they were created
+ * in, e.g. the only popup you are allowed to destroy at all times is the
+ * topmost one.
+ *
+ * When compositors choose to dismiss a popup, they may dismiss every
+ * nested grabbing popup as well. When a compositor dismisses popups, it
+ * will follow the same dismissing order as required from the client.
+ *
+ * The parent of a grabbing popup must either be another xdg_popup with an
+ * active explicit grab, or an xdg_popup or xdg_toplevel, if there are no
+ * explicit grabs already taken.
+ *
+ * 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.
