Subject: [PATCH] fixes a small bug on RotationStackedAnimation which uses a
 wrong delta for the back widget rotation animation angle. The back widget was
 rotating from 90 (0.25 * 360) degrees to 180 (0.5 * 360), but the correct
 rotation is from 270 (0.75 * 360) to 360 (1.00 * 360). This patch also fixes
 code indentation.
