Doc: mention that some filtered events need to be explicitly accepted
QKeyEvent's detailed description already documents this:
"A key event contains a special accept flag that indicates whether the
receiver will handle the key event. This flag is set by default for
QEvent::KeyPress and QEvent::KeyRelease, so there is no need to call
accept() when acting on a key event. For QEvent::ShortcutOverride the
receiver needs to explicitly accept the event to trigger the override.
Calling ignore() on a key event will propagate it to the parent widget.
The event is propagated up the parent widget chain until a widget
accepts it or an event filter consumes it."
However, someone looking at eventFilter() won't see this, resulting in
the shortcut not being consumed and propagating elsewhere, so mention
it in the docs for eventFilter() too.
