Subject: [PATCH] cocoa: only report mouse movements when window is not being
 dragged
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

even though the mouse doesn’t move relative to the window itself, when
the window is being dragged, some outliers are still reported and
trigger the OSC.
