* Tests that epoxy correctly handles an EGL and GLX implementation |
|
||||||
* that return different function pointers between the two. |
|
||||||
* |
|
||||||
* This is the case for EGL and GLX on nvidia binary drivers |
|
||||||
* currently, but is also the case if someone has nvidia binary GLX |
|
||||||
* installed but still has Mesa (software) EGL installed. This seems |
|
