[osg-users] setGLExtensionFuncPtr priority

[Julien Valentin]

Please, read the original problem and the example before randomly citing specs.
The problem concerns linux nvidia propriétary driver (not win32)
I admit I misnamed this thread but it's not a reason for acting in a such 'Mr-I-know-all" fashion: 
How can you say there's something wrong in using glGetTextureHandle whereas the exampleosgbindlesstext should work on your plateform?

This is exactly the type of behavior I can't stand from guys naming themself "professionnal".

I can't find any note of core promotion, or a function prototype for glGetTextureHandle (no NV no ARB), so I would not call a driver bug if it does something not entirely as expected.Regards, Laurens.
