 * Test "Jumping backward to the start of a DisplayObject's lifetime after dynamic transformation"
 *
 * run as ./displaylist_depths_test8
 *
 * Timeline:
 * 
 *   Frame  | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
 *  --------+---+---+---+---+---+---+---+
 *   Event  |   |Pt*|   | T |   |   | J |
 * 
 *  P = place (by PlaceObject2)
 *  T = transform matrix (by PlaceObject2)
 *  t = transform matrix (by ActionScript)
 *  M = move to another (or same) depth (by swapDepth)
 *  J = jump
 *  * = jump target
 * 
 * Description:
 * 
 *  frame2: DisplayObject placed at depth -16381 at position (10,200);
 *          increment _y += 2 using ActionScript.
 *  frame4: try to transform the DisplayObject to the right (50,200)
 *  frame7: jump back to frame 2 
 * 
 * Expected behaviour:
 * 
 *  * In frame 2 the instance is positioned at 10,202
 *    ActionScript matrix transform in frame2 prevent subsequent static transformations to apply:
 *  * In frames 4,5,6 and 7 the instance is still positioned at 10,202 
 *    (static transformations are disabled as the instance has been transformed by script in frame 2)
 *  * After the jump we have the same instances at depth -16381, still positioned at 10,202
 *  * A single instance has been constructed in total.
 *  * Actions in jump-target frame are executed after actions following the gotoAndPlay() call.
 *
