/*
For the particular case of a boundary within a text node containing
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 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.
