Hi Sam,

Thanks for implementing this!

It worked pretty well except the 2 issues I list below:
1. I think the offset in the returned range should be the character/caret
offset relative to the whole element, not relative to the viewpoint.
Please see the attached file caretRangeFromPointWithoutScroll.html for detailed
explanation.

2. If I pass in event.clientX + document.body.scrollLeft and 
event.clientY + document.body.scrollTop as the x-axis and y-axis to
caretRangeFromPoint(), there is a possibility that the range is null which
should not. 
Please see attached file caretRangeFromPointWithScroll.html for detailed
explanation.

Please let me know if I mis-understood anything, or the code needs a bit tweak.

Thanks,
Xiaomei
