Changed drag area API to a hit-testing API. There were several good arguments for this: it's how Windows works with WM_NCHITTEST, SDL doesn't need to manage a list of rects, it allows more control over the regions (how do you use rects to cleanly surround a circular button?), the callback can be more optimized than a iterating a list of rects, and you don't have to send an updated list of rects whenever the window resizes or layout changes.
