Subject: [PATCH 14/28] Accessibility event is sent on item's geometry change
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In case of enabled accessibility, whenever the geometry
of a QQuickItem changes, accessibility module is notified
by a LocationChange event. This enables responding to this
by for example moving the accessibility frame on the screen.

Task-number: QTBUG-79611
Change-Id: I808e835384ef42bba2e9aabecf4be3cda07859fe
