Steps to reproduce:

1. Go to the contentEditable div in http://thottingal.in/projects/js/jquery.ime/examples/
2. Move the cursor to the end of the content, and press Enter to create a new paragraph (actually <p><br></p> in most browsers).
3. Enable Malayalam input, and press 'x'
4. Observe that the text gets inserted at the very start of the contentEditable text, instead of where the cursor is.

This happens because in jquery.ime.js#getDivCaretPosition, traverseTextNodes only checks node === range.startContainer in text nodes. So in the case outlined above, it fails to detect the selection range, and hence the default range of 0-0 is returned.

More generally, the "position" values used by getDivCaretPosition / setDivCaretPosition only count text characters (i.e. code units in text nodes). This would need to change in order to represent offsets that do not lie within a text node. Adding one for each element node entry/exit looks like it can solve this.
