[osg-users] setGLExtensionFuncPtr priority

[Voerman, L.]

Hi Julien,
on my windows system (win 10 / nvidia driver 388.13 / geforce gtx 1080)

0x0000000000000000  glGetTextureHandle
0x00000000672f2a30  glGetTextureHandleARB
0x00000000672f2ab0  glGetTextureHandleNV

I think using glGetTextureHandle is not according to spec.
Laurens.
