I believe we're making some last-minute tweaks to how Flex 3 works with graphical skins. I believe we examine the scale9 rectangle.

OK, I am soooooo close. I think the only remaining compatibility issue is that Flex 3 seems to auto-size a Button to match the dimensions of its skin (very handy) but Flex 2 doesn't. I would like to avoid setting the sizes of my default buttons because that will make things much harder to restyle and makes runtime style switching a pretty huge pain. If I don't provide sizes though, the Buttons look wonky in Flex 2. Any suggestions? Is there a way to detect the dimensions of a graphical skin?
