Fixed Bounding Box

[C$]

First of all, I want to say that I'm a huge fan of Zoetrope.  The more I play around with it the more I like it!

But I was curious, why doesn't a sprite's bounding box change when it gets rotated?  Now, I'm not saying this behavior is incorrect (and it's easy enough to work around by just using square sprites), but I wondered what the benefit of keeping the bounding box fixed is.  Does it make the collision detection a lot easier this way?

Thanks Again!
