good call. On a  1.66Ghz PPC

(#_glVertex3f a b c) takes about 3 us

(defun glVertex3f (a b c)
   (#_glVertex3f a b c))

(glVertex3f a b c) with glVertex3f not inline about 4 us

(glVertex3f a b c) with inline is back to 3 us

Oddly, my much faster Intel Mac runs this slower


That leaves, the unfortunately much harder, problem of finding a way  
to generate the defun from the famework definition.
