[osg-users] setGLExtensionFuncPtr priority

[Julien Valentin]

Thank for your answer but there aren't any relation with this driver issue:
-osgbinlesstext include ARB_bindless_texture (perhaps there incompitibiliites due to the use of uint64 but for nv all is good)
-osgbinlesstext don't rely on UniformHandleui64
-AFAIK osgbindless has never get problem under win32 so it's really a driver bug

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.
