[Drawkit] DKGuide position mayhem

[Graham Cox]

One thing to note in general is that if you ever have a method that  
returns a float, it is essential that anything that needs to call it  
imports its class's header so that it has the correct prototype. If  
not you get bizarre results that can even cause memory corruption, not  
just bad return values, yet the compiler will give absolutely no  
warning. I have run into this on two occasions so far.

cheers, Graham
