  22  * Test "Jumping backward to the midle of a DisplayObject's lifetime after static transformation"
  23  *
  24  * run as ./displaylist_depths_test4
  25  *
  26  * Timeline:
  27  *
  28  *   Frame  | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
  29  *  --------+---+---+---+---+---+---+---+
  30  *   Event  |   | P |   | T*| T |   | J |
  31  *
  32  *  P = place (by PlaceObject2)
  33  *  T = transform matrix (by PlaceObject2)
  34  *  J = jump
  35  *  * = jump target
  36  *
  37  * Description:
  38  *
  39  *  frame2: DisplayObject placed at depth -16381 at position (10,200)
  40  *  frame4: position of instance at depth -16381 shifted to the right (50,200)
  41  *  frame5: position of instance at depth -16381 shifted to the right (100,200)
  42  *  frame7: jump back to frame 4
  43  *
  44  * Expected behaviour on jump back:
  45  *
  46  *  Before the jump we have a single instance at depth -16381 and position 100,200.
  47  *  After the jump we have the same instances at depth -16381, repositioned at 50,200.
  48  *  A single instance has been constructed in total.
  49  *  Soft references to the instance created before the jump-back still point to the same instance.
