/*!
    When working with bookmarks, the run block offset does not always adequately represent the
    location of the bookmark. For example, if the user bookmarks the same place in the doc with
    several bookmarks, the run offsets for each associated run will be different, but most of the
    time we are interested in the offset to the left or right of all stacked up bookmarks. Similarly,
    a bookmark that is immediately after a start of block needs to be treated in certain situations
    as if the block strux was also sellected. This function implements the necessary logic.

    In general, when we jump to bookmarks, we go to the range in between the two bookmark
    object. However, for purposes of TOCs, we are interested in the range that is just outside the
    two objects.

    \parameter bAfter: indicates if we want offset to the right (true) or left (false) of the
                       bookmark

    \return: the return value is document offset of the bookmarked position

  Draw end-of-paragraph Run graphical representation

  Draws the pilcrow character (reverse P) in show paragraphs mode.
  \fixme Make it use the same typeface as preceding text.
  \note This _draw function is special in that it does (partly) lookup
  as well. That's because the pilcrow's typeface is controlled by the
  preceding character. Eventually, when the PT learns about EOP, it
  should be possible to just deal with this in the lookup function.
