commit aa39868d81e25078a2a16dd7a214c5c31e1fb3f7
Author: jbauman <jbauman@chromium.org>

Remove flash of white borders on maximize/fullscreen

With Aero the default WM_NCPAINT doesn't clear the nonclient area, so on
resize it looks ugly when it temporarily becomes visible. Chrome can
clear it itself on WM_NCPAINT.
