| /** WallpaperBitmapPrimitive2D class |
| |
| 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. |
