            This is a specialized primtive for the Wallpaper definitions included in
            VCL and Metafiles. The extraordinary about the bitmap definition part of
            the Wallpaper is that it uses PIXEL size of the given Bitmap and not
            the logic and/or discrete size derived by PrefMapMode/PrefSize methods.
            To emulate this, a ViewTransformation dependent primitive is needed which
            takes over the correct scaling(s).

            Since a specialized primitive is needed anyways, i opted to also add the
            layouting which is dependent from WallpaperStyle; thus it does not need
            to be handled anywhere else in the future.
