/** WallpaperBitmapPrimitive2D class
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.
