Accessibility APIs sensitive to whether an NSView isFlipped

Hello all,

I just noticed by debugging that when hit testing, or when I return a AXPosition, the accessibility APIs peek at my NSView to look at whether it returns YES for |-(BOOL)isFlipped| and adjust accordingly.

I had assumed that, when returning an AXPosition for something deep down in my hierarchy, that I would always return a cocoa coordinate, but I noticed that it depends on what the topmost NSView's coordinate system is like.

Note that a |accessibilityHitTest:| message can be sent and return a custom object deep down the view, that Cocoa can't see. Since this custom object might not know what *anything* about the view's internal properties, I think it would make more sense to say that the APIs always expect a cocoa coordinate, or vice versa.

Anyway, some kind of comment about this automatic adjusting in the accessibility docs would make sense.

Thanks,
