Well, glGenBuffersARB_p is gone in OpenGL::Modern because any OpenGL in the last (15 years?) has glGenBuffers which is the same thing by its now-official name, and I don't know if new OpenGLs would acknowledge the name glGenBuffersARB. But, thanks for pointing that out, because maybe I could check for it to provide buffer Perl objects when using using the original OpenGL module. But, what uses buffer objects in 1.4? Are all the rest of OpenGL 2's APIs provided as optional extensions on 1.4?
