Is there some straightforward way of wrapping a CGPoint so I can put
it in an NSArray? I don't want to use a C array because I want to have
fast enumeration available. Or should I just write a simple NSPoint -
CGPoint conversion method?

NSPoint and CGPoint are structs that are essentially the same. You can convert between them with a simple cast:

NSPoint point = *(NSPoint *)&myCGPoint;

<http://developer.apple.com/documentation/Cocoa/Conceptual/CocoaDrawingGuide/QuartzOpenGL/chapter_10_section_2.html >

You can also use the function NSPointFromCGPoint() which does the exact same thing for you:

NSPoint point = NSPointFromCGPoint(myCGPoint);

(Declared in NSGeometry.h)
