WPF/IronPythonで、ViewboxUnits を Absolute で Tile を実行する。
ImageBrush のViewBoxの使い方に慣れてきました。
つぎのBlogを参考にさせて頂きました。

創造的プログラミングと粘土細工 ⇒ 【WPF】Visibilityってご存じですよね？
http://pro.art55.jp/?eid=969079
画像の上で、マウスを押しながら移動すると、画像がそれに合わせて移動します。
マウス右クリックで、Coverを表示しません( Visibility.Collapsed )
今度は、Tile の上でマウスのホイールを回すと Coverが表示されます( Visibility.Visible )
もう一度、マウス右クリックで Coverが表示されます( Visibility.Visible )
マウスカーソルの形も変化します。
