Crafty.init(300, 300);
Crafty.log(Crafty.isometric.size(64).area());
// { x: { start: 0, end: -5 }, y: { start: 1, end: -17.75 } }

I haven't dealt with the isometric code much. From looking at the source here, I notice it's referring to the viewport in several places.

Are you defining any viewport transformations? One guess is that there might be some assumptions in the isometric code that don't hold under certain transformations.

Hmm, certainly on the surface it seems like something is broken. I'll try to dig into what's going on here this weekend.
