Git commit 9417a76132b5af438d25870c479e60518d7b0270 by Martin Gräßlin. Committed on 11/05/2012 at 19:55. Pushed by graesslin into branch 'master'. Ensure ScreenTransformation matrix is reset after rendering cube Cube effect modifies the ScreenTransformation matrix. While each window resets the matrix on a global level it's not reset. That means if the last rendered window had the screen rotated the ScreenTransformation keeps the rotation even after the cube ended. This causes a rotated window in e.g. TaskbarThumbnails.
