Avoid VNC updates for offscreen windows

Windows aren't always directly shown, e.g. when the desktop is
composited. We should not be sending screen updates for these as the
framebuffer didn't actually change.

In the case of CopyWindow, we're even sending the wrong screen data,
which is how this bug was discovered.
