[Drawkit] permanent objects

[James Maxwell]

Thanks, Uli.

Well, yes, t is basically a ruler, but looking into NSRulerView, it  
seems like it might be a bit complicated to do what I'm planning on  
doing. I want multiple horizontal rulers in my new, and I'm going to  
be creating these dynamically, as well - basically, whenever a new  
guide is added, a new "ruler" will be added, starting again from zero  
(well, one actually). I'll dig around to see if Graham used something  
other than the NSRulerView (i.e.,  a subclass), but I think it will  
behave in basically the same way. The other thing is that I'm going to  
allow the user to change the division on each ruler, independently of  
the others (it's a musical time thing). I kind of feel like  
NSRulerViews will become cumbersome doing this kind of thing... But  
I'll look more thoroughly into NSRulerView, or whatever Graham is  
using, before I rule it out (pun honestly not intended!).

cheers,

J.
