QPainterPath set operations deprecated in Qt 4.8

From this blog post about Qt 4.8

http://labs.qt.nokia.com/2011/05/12/...evel-the-list/

it says that QPainterPath set operations are deprecated from now on. So what does this say about set operations on QPolygonF and other similar classes. I read their code and found that they used to use QPainterPath for implementing these methods.

I think it won't hurt to ask directly there.
IMHO, if they gonna mark the method as deprecated, I doubt that they will use it in their code, maybe they are going to provide new implementation for set operations in Polygon class.

Well by the time I read it, commenting was closed on the blog.
