[PATCH v3 6/6] composite: Recompute clipping when changing between manual and automatic redirection

[ville.syrjala at nokia.com]

From: Ville Syrjälä <ville.syrjala at nokia.com>

Call compMarkWindows() when changing between manual and automatic
redirection modes. Otherwise the window clipping won't be recomputed
correctly.
