NAME
       CopySBitMap --   Syncronize layer window with contents of

   SYNOPSIS
       CopySBitMap( layer )
                     a0

        void CopySBitMap(struct layer *);

   FUNCTION
        This is the inverse of syncsbitmap.
       Copy all bits from SuperBitMap to layer bounds.
        This is used for those functions that do not
        want to deal with the cliprect structures but do want
        to be able to work with a SuperBitMap layer.

   INPUTS
        layer - pointer to a SuperBitMap layer
            The layer must already be locked by the caller.
