The expressive power of MapGuide Tooltips redux

Over a year ago, I wrote about how you can have really powerful tooltips in MapGuide with some knowledge of HTML and the FDO expression language, with one major caveat:

You can't have interactive content in the AJAX viewer.

Well I've finally tackled this problem and implemented "sticky" tooltips for the AJAX viewer, so now you can have your Google Charts or Youtube videos in your AJAX viewer tooltips and be able to interact with them

I'm hoping to get this in for the 2.2 release of MapGuide Open Source. If you can't wait, and know how to apply diffs, you can grab the patch here
