 * Test "Jumping backward to the start of a DisplayObject's lifetime after static transformation"
 *
 * run as ./displaylist_depths_test5
 *
 * Timeline:
 * 
 *   Frame  | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
 *  --------+---+---+---+---+---+---+---+
 *   Event  |   | P*|   | T |   |   | J |
 * 
 *  P = place (by PlaceObject2)
 *  T = transform matrix (by PlaceObject2)
 *  J = jump
 *  * = jump target
 * 
 * Description:
 * 
 *  frame2: DisplayObject placed at depth -16381 at position (10,200)
 *  frame4: position of instance at depth -16381 shifted to the right (50,200)
 *  frame7: jump back to frame 2
 * 
 * Expected behaviour on jump back:
 * 
 *  Before the jump we have a single instance at depth -16381 and position 50,200.
 *  After the jump we have the same instances at depth -16381, repositioned at 10,200.
 *  A single instance has been constructed in total.
 *  Soft references to the instance created before the jump-back still point to the same instance.
