so we (or I ;-) have to:
	1.) check  the manual functions
		- guess i _just_ did it ;-)
	2.) add typed Buffer (FloatBuffer, ...) support
	    within C2J for typed arrays ..

as we allready discussed and as you allready pushed
we might create a new layer, which wraps all
glx/wgl/.. functions. 

such a layer therefore wraps the OpenGL / OS-Specific stuff 

may be we can call it gl4java.GLOSFunc

e.g:

gl4java.GLOSFunc.GetProcAddress
   #ifdef _X11_
	glXGetProcAddress
   #elif _WIN32_
	wglGetProcAddress

and so on ..

BUT ONLY FOR SUCH FUNCTION,
which are mention and spec at the ARB,
so they are avaiable on "all" plattforms:
	Unices/X11 (glx), Win32 (wgl), MacOSX (???)

cheers, sven
