  30     // The layout representation is the following:
  31     //
  32     // - We assume that the anchor type is at-para for such fly frames.
  33     //
  34     // - We also assume that AutoSize is true for such fly frames.
  35     //
  36     // - SwFlyAtContentFrame derives from SwFlowFrame to be able to split in general.
  37     //
  38     // - Both the master fly and the follow flys need an anchor. At the same time, we want all text
  39     // of the anchor frame to be wrapped around the last follow fly frame, for Word compatibility.
  40     // These are solved by splitting the anchor frame as many times as needed, always at
  41     // TextFrameIndex 0.
  42     //
  43     // - The vertical offset is only considered on the master fly, all the follow flys ignore it, so
  44     // they start at the top of a next page.
