If you're targeting Leopard then you can use the NS_BUILD_32_LIKE_64
flag and use NSRect/Point/Size and CGRect/Point/Size interchangeably
without the cast or the inline conversion functions. Here's a how-to http://theocacao.com/document.page/552

Is there some straightforward way of wrapping a CGPoint so I can put

NSPoint and CGPoint are structs that are essentially the same. You
can
convert between them with a simple cast:
NSPoint point = *(NSPoint *)&myCGPoint;

You can also use the function NSPointFromCGPoint() which does the
exact
same thing for you:
NSPoint point = NSPointFromCGPoint(myCGPoint);
(Declared in NSGeometry.h)
The function is actually implemented a bit better than the cast
above, in
that the function does not violate strict aliasing[1].
