                        For the particular case of a boundary within a text node containing rendered line breaks (within a
                        <pre> 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 approach used 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.

 *    - sandboxing of physical documents causes that the dom isn't accessible anymore from the outside (iframe.contentWindow, ...)
 *    - setting the "allow-same-origin" flag would fix that, but then still javascript and dom events refuse to fire
 *    - therefore the "allow-scripts" flag is needed, which then would deactivate any security, as the js executed inside the iframe

     *  - We can't use HTML5 sandbox for now:
     *    setting it causes that the iframe's dom can't be accessed from the outside
     *    Therefore we need to set the "allow-same-origin" flag which enables accessing the iframe's dom
     *    But then there's another problem, DOM events (focus, blur, change, keypress, ...) aren't fired.
     *    In order to make this happen we need to set the "allow-scripts" flag.
     *    A combination of allow-scripts and allow-same-origin is almost the same as setting no sandbox attribute at all.
     *  - Chrome & Safari, doesn't seem to support sandboxing correctly when the iframe's html is inlined (no physical document)
     *  - IE needs to have the security="restricted" attribute set before the iframe is
     *    inserted into the dom tree
     *  - Believe it or not but in IE "security" in document.createElement("iframe") is false, even
     *    though it supports it
     *  - When an iframe has security="restricted", in IE eval() & execScript() don't work anymore
     *  - IE doesn't fire the onload event when the content is inlined in the src attribute, therefore we rely
     *    on the onreadystatechange event
