+
+            This is a specialized primitive 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.
