server: Correctly expose composited parent window and its child on position change.

Skip redrawing the composited child window when the window rect and visible region stays the same, since we're taking the union of the old and new visible regions. Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=53153Signed-off-by: 's avatarJinoh Kang <jinoh.kang.kr@gmail.com>
