Well, you probably wouldn't be able to construct a UIKit::Point from a CoreGraphics::Point in the first place (these aren't C++ libraries but let's just go along for the analogy) if they didn't know about each other. You'd have to strip out the X and Y yourself, and this is the moment where you should be wondering if that's legal to do.
And if the libraries do know about each other then it's even better, because you can just say
CoreGraphics::Point cgp = CoreGraphics::Point(0, 0);
UIKit::Point p = UIKit::Point(cgp);
and p could already be in the right coordinate frame.
Anyways, this isn't some constant thing. Java developers typically like abstraction, ruby guys like passing raw hashes and strings/symbols everywhere. My preferences change based on language, codebase size, and how many people I'm going to be working with.
