      38             :             VCL and Metafiles. The extraordinary about the bitmap definition part of
      39             :             the Wallpaper is that it uses PIXEL size of the given Bitmap and not
      40             :             the logic and/or discrete size derived by PrefMapMode/PrefSize methods.
      41             :             To emulate this, a ViewTransformation dependent primitive is needed which
      42             :             takes over the correct scaling(s).
      43             : 
      44             :             Since a specialized primitive is needed anyways, i opted to also add the
      45             :             layouting which is dependent from WallpaperStyle; thus it does not need
      46             :             to be handled anywhere else in the future.
