That's exactly what i'm doing too, except that i don't let the app
decide the world it's running into.

But i think you missed the point of build-time dependencies, No X
headers = no QPolygonF, .... why?
A polygon is "just" defined by a set of ordered point in a 2D space.
Anyway, i'm not here to blame Qt, Qt provides graphically rendererable
polygon, not mathematically-defined polygons....

Works great here too.
