title: Eclipse Plugin Dev: How to use new Rich Text Hovers (since 3.4)
body: <p>I've implemented plain text hovers in my plugin with ITextHover. And now I want to use new eclipse 3.4 feature - Rich text hovers with text styles, images and actions.But I can't find articles/examples about it. What interfaces should I use and where?
  I found ITextHoverExtension2 interface, but can't find how to create hover objects (what class should they be?) and what interface should catch them?</p>
