-                    element, for example), we need a slightly complicated approach to get the boundary's offset in IE. The
-                    facts:
-                    
-                    - Each line break is represented as \r in the text node's data/nodeValue properties
-                    - Each line break is represented as \r\n in the TextRange's 'text' property
-                    - The 'text' property of the TextRange does not contain trailing line breaks
-                    
-                    To get round the problem presented by the final fact above, we can use the fact that TextRange's
-                    moveStart() and moveEnd() methods return the actual number of characters moved, which is not necessarily
-                    the same as the number of characters it was instructed to move. The simplest approach is to use this to
-                    store the characters moved when moving both the start and end of the range to the start of the document
-                    body and subtracting the start offset from the end offset (the "move-negative-gazillion" method).
-                    However, this is extremely slow when the document is large and the range is near the end of it. Clearly
-                    doing the mirror image (i.e. moving the range boundaries to the end of the document) has the same
-                    problem.
-                    
-                    Another approach that works is to use moveStart() to move the start boundary of the range up to the end
-                    boundary one character at a time and incrementing a counter with the value returned by the moveStart()
-                    call. However, the check for whether the start boundary has reached the end boundary is expensive, so
-                    this method is slow (although unlike "move-negative-gazillion" is largely unaffected by the location of
-                    the range within the document).
-                    
-                    The method below is a hybrid of the two methods above. It uses the fact that a string containing the
-                    TextRange's 'text' property with each \r\n converted to a single \r character cannot be longer than the
-                    text of the TextRange, so the start of the range is moved that length initially and then a character at
-                    a time to make up for any trailing line breaks not contained in the 'text' property. This has good
-                    performance in most situations compared to the previous two methods.
