I noticed some of the cl-opengl code uses things like (:pointer gl:double) instead of :pointer for defcfun parameter types, is this something the generated bindings should do also? (and if so, is (:pointer (:pointer foo)) correct syntax for foo**?) Wrapper generator handles either option, just wasn't sure what benefits it had, and if it was worth dropping cffi 0.9.1 support for.
I started doing this for new functions that I added bindings for because it was more self-documenting. The previous convention had been to add the pointer type in comments after the argument, which is less than ideal IMHO.
Personally I prefer to parameterize the pointer type, but it does indeed require a more recent CFFI. One advantage to this is that when a type checking system is (someday) added to CFFI, the OpenGL bindings should be able to take advantage of it if the pointers are typed.
