Hi !

Well I'm a bit lost now. I decided that I wanted to do the  following things :
- Create a table with all the functions I'm using with the minimal required OpenGL version so that I know which ones are essential (and therefore add a minimal required OpenGL version to use my library).
- For those that can be dealt with another way, simply add a version check in my library and switch to using a different function when the version is too low.

First thing to do was to create the table of OpenGL compatibility :



But when checking the versions I noticed that actually, the function that doesn't work should work :



And for completeness' sake, here is the OpenGL version on this computer (as given by OpenGL Extension Viewer) :



Perhaps I'm missing something on how version are checked in the documentation, but it seems to me that this function should work...

Thanks for your help !
