Draft: Some changes about testQuickTilingPointerMove

We need to attach a new image after the tiling window, so that updateElectricGeometryRestore can obtain the same framegeometry as the framegeometry obtained during actual runtime.

Now testQuickTilingPointerMove can detect the error：

If the user wants to move a tiled window but changes their mind and tiles the window back to the previous position, quickTileGeometryRestore() will return an error value beacause m_electricMaximizing is true and the m_electricGeometryRestore is the same as the geometry of the window in the last tiled mode.
