[MacRuby-devel] Is CoreText Fully Support

Hi I'm doing some work with CoreText with macruby ,and i had some question 1. CTline and some other `struct` does not have a ruby class ,the ctline.class is __NSCFType , not like the CGRect struct,in macruby ,the class is CGRecct ,so i can reopen the class ,and add some help methods. 2. the CTRunGetStringRange should return a CFRange but it return a class named Boxed can i wrap the CoreText in macruby ? and some suggestions ?? thanks
