 * Test "Jumping backward to the midle of a DisplayObject's lifetime after swap and swap back"
 *
 * run as ./displaylist_depths_test6
 *
 * Timeline:
 * 
 *   Frame  | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
 *  --------+---+---+---+---+---+---+---+
 *   Event  |   |PMM|   | T | T*|   | J |
 * 
 *  P = place (by PlaceObject2)
 *  T = transform matrix (by PlaceObject2)
 *  M = move to another depth (by swapDepth)
 *  J = jump
 *  * = jump target
 * 
 * Description:
 * 
 *  frame2: DisplayObject placed at depth -16381 at position (10,200);
 *          swap the DisplayObject to depth -10, and then swap it back to -16381;
 *  frame4: try to transform the DisplayObject to the right (50,200)
 *  frame5: try to transform the DisplayObject to the right (200,200)
 *  frame7: jump back to frame 5 and stop
 * 
 * Expected behaviour:
 * 
 *  After depth swapping in frame2, even if final depth is the same as the original one, static transformations in frame4 and frame5 have no effect.
 *  Before the jump we have a single instance at depth -16381 and position 10,200.
 *  After the jump we have the same instances at depth -16381, and still positioned at 10,200.
 *  A single instance has been constructed in total.
 *
