title: Confusing (x, y) origins with sub-views in interface builder
body: <p>I have a view in interface builder, and then a subview within that view.  I place the sub-view visually near the upper left corner within its parent.  I would therefore expect the x, y coordinates of the sub-views frame to be something close to (20,20), but instead IB tells me it is something like (230,432).  If I then adjust the X, Y coords in the properties window to something like (20,20), the sub-view flies off the screen towards the upper-left...  What is the deal?  BTW, it is an iPad specific view size, where the top/parent view is sized 768x1004.</p>
