  22  * Test "Jumping backward to the midle of a DisplayObject's lifetime after moving it to a static depth"
  23  *
  24  * run as ./displaylist_depths_test3
  25  *
  26  * Timeline:
  27  *
  28  *   Frame  | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
  29  *  --------+---+---+---+---+---+---+---+
  30  *   Event  |   | P |   | T*| T | M | J |
  31  *
  32  *  P = place (by PlaceObject2)
  33  *  T = transform matrix (by PlaceObject2)
  34  *  M = move to another depth (by swapDepth)
  35  *  J = jump
  36  *  * = jump target
  37  *
  38  * Description:
  39  *
  40  *  frame2: DisplayObject placed at depth -16381 at position (10,200)
  41  *  frame4: position of instance at depth -16381 shifted to the right (50,200)
  42  *  frame5: position of instance at depth -16381 shifted to the right (100,200)
  43  *  frame6: depth of instance changed to -10 (static zone)
  44  *  frame7: jump back to frame 4 and stop.
  45  *
  46  * Expected behaviour on jump back:
  47  *
  48  *  Before the jump we have a single instance at depth -10 and position 100,200.
  49  *  After the jump we have a single instances at depth -16381 and position 20,200.
  50  *  Two distinct instances have been constructed in total.
  51  *  Soft references to the old instance created before the jump-back now point to the new instance.
