That looks better :-)

That's true. High efficiency spatial datastructures are hard to 
refactor so better to keep it simple in the beginning. Leave 
yourself room to experiment with different class hierarchies etc.

Just make sure that you pick an architecture that allows you to 
use spatial datastructures later on!

Another option is to use 2 passes.

Pass 1: collects geometric information, could even use virtual 
function calls.

Pass 2: highly optimized algorithm for calculating layout 
plugin-style (meaning you can start with something simple and 
just replace it wholesale since it doesn't depend on the object 

Then you can think more about usability and less about 
performance. Sure, there is a performance price, but flexibility 
is more important in the first iterations. KISS until the design 
is locked down FTW.
