* 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.
*
* 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.

* If the popup is repositioned in response to a configure event for its
* parent, the client should send an xdg_positioner.set_parent_configure
* and possibly an xdg_positioner.set_parent_size request to allow the
