If window gets exposed but clipboxes doesn't change drivers would avoid color key fill. This makes XResizeWindo&co to lose colorkey if background is painted. To help drivers to avoid filling colorkey for each put server can provide helper function if there is exposed areas. Server can subtract exposed areas from filled region. As a side effect we can avoid useless color key fills if window only moves in screen without background fills. v3: * Change tracking to filled area to account for client initiated clip changes * Make overlaid XvPutImage behavior like textured XvPutImage or PutImage * Make region dynamically allocated only when required. v4: * Simplify new driver interface to reduce duplicate code Signed-off-by: Pauli Nieminen <ext-pauli.nieminen@nokia.com> Reviewed-by: Ville Syrjälä <ville.syrjala@nokia.com>
