Apply a kludge to initialize the composite wrapper before DamageSetup. If

Browse source 
not, DamageSetup will wrap some operations first, and the cw
    initializes during ExtensionInit, so cw comes higher in the wrapping
    chain. cw going first will result in damage getting confused when the
    drawables get changed around.
