So for the example above, if you set the view to have the size { 200, 300 }, it would change that to { 100, 200 }, despite { 200, 300 } being a perfectly legal size under those constraints. I don’t want to find what the system thinks is the “one true” size — I’m just trying to figure out the limits so I can keep the sizes legal, that’s all.

I am getting a bit befuddled. Is the following what we have:
1. A certain view hierarchy managed by a set of constraints.
2. A certain Charles, who wishes to programatically modify (maximise?) the size of one (or more) of the managed views in such a way that it doesn't cause a layout exception.
3. In order to perform 2, Charles wants to be able to query the layout for a given view to determine its (maximum?) allowed size.
