* Status Window handling
*
* A status window is a small window attached to the toplevel
* that is used to display information to the user about the
* current input operation.
*
* We claim the toplevel's status window for an input context if:
*
* A) The input context has a toplevel
* B) The input context has the focus
* C) The input context has an XIC associated with it
*
* Tracking A) and C) is pretty reliable since we
* compute A) and create the XIC for C) ourselves.
* For B) we basically have to depend on our callers
* calling ::focus-in and ::focus-out at the right time.
*
* The toplevel is computed by walking up the CdkWindow
* hierarchy from context->client_window until we find a
* window that is owned by some widget, and then calling
* ctk_widget_get_toplevel() on that widget. This should
* handle both cases where we might have CdkWindows without widgets,
* and cases where CtkWidgets have strange window hierarchies
* (like a torn off CtkHandleBox.)
*
* The status window is visible if and only if there is text
* for it; whenever a new CtkIMContextXIM claims the status
* window, we blank out any existing text. We actually only
* create a CtkWindow for the status window the first time
* it is shown; this is an important optimization when we are
* using XIM with something like a simple compose-key input
* method that never needs a status window.
