Title: FramedCloud Popup: adjust the insertion point.

Using `Popup.FramedCloud` the insertion point is moved one pixel in some cases (depending on relative position is used):
* "tl": 1px to up
* "bl": 1px to right
* "tr": 1px to left
* "br": is ok!

and in "tl" the border around the stem is two pixels instead of one.

See http://jsfiddle.net/jorix/kUPXr/ (need to zoom your browser to see the mismatches) and dev+patch: http://jsfiddle.net/jorix/kPKzM/ (fixed)

(some time ago I saw some of these mismatches so is not only a problem of the current version)
