Does this work with modern jQuery?

I've researched all (x, y) caret position plugins on GitHub and this is the oldest. Would it work with jQuery 1.9?

Haven't needed this in a good long while as you can see by the lack of activity :)

Just tested this with 1.9 (see last commit) and it seems to work fine.
If you're targeting IE9 plus, I believe you could even get rid of the test for document.selection as it comes with selectionStart/selectionEnd

I noticed there may be an issue with calculating the height over blank lines, which I don't have time to fix currently, although if you raise an issue I'll take a look when I can.
