Just use NSPointerArray...
Just as is the case with an array of NSValue objects, NSPointerArray doesn't
help here -- it makes no guarantees about how the objects will be arranged in
memory, and NSBezierPath needs them to be

Another possible approach is simply use a NSMutableArray full of NSValue

I don't believe that'll work - storing everything in NSValue objects will end

The easiest way (and Objective-C-ish way) is to use a NSMutableData object
with the NSPointArray as its data. Whenever you want to add points, just
resize the NSMutableData object to 'sizeof (NSPoint)' * total number of
points, and use '(NSPointArray) [data mutableBytes]' as a pointer to

Why not just accumulate the points directly into NSBezierPath? It can be
thought of as an array of points in a sense. Unless there's a compelling need
to have the points themselves available in addition to the bezier path, just
cut out the middle man (and it's not difficult to retrieve the
