Hi again,<br><br>I&#39;ve been working with a number of OpenGL 2.0 concepts such as shader programs, and I&#39;ve come across a bit of a snag with ATI&#39;s OpenGL 2.0 support.&nbsp; <br><br>The shader programs work fine with the 
libGL.so as supplied by nvidia (on my home machine), but when using libGL.so from ATI on my work machine, functions such as create-shader fail, as there is no such symbol in the library.&nbsp; Using glXGetProcAddress to get the function pointer for glCreateShader, however, is the required work around for the ATI library.
<br><br>I was tempted to create a cl-glew library binding, however this won&#39;t really work that well, as _that_ library also doesn&#39;t include all the symbols, and relies on C preprocessor macros heavily to do the right thing.&nbsp; 
<br><br>Anyways, I was thinking instead of modifying cl-opengl instead to (perhaps dependant on some switch?) use glXGetProcAddress for those functions that aren&#39;t directly callable, memoized of course.<br><br>Does this sort of thing make sense in this context?&nbsp; It&#39;s been a while since I&#39;ve done a lot of lisp, and I&#39;m also not super familiar with FFIs, so I want to make sure I do this the lispyiest way possible.
