Hi Dan,

>  I had to download and slightly modify the Khronos glcorearb.h file


That is actually what I'm trying to avoid. Having another dependency which 
users have to download and modify.

There is only one gl/GL.h in windows. It is the "modern" one since it will 
never be updated. It does not give you anything past OpenGL1.1 i think. 
With my fix, users would still need to manually use the Open GL extension 
functions to access all the latest functionality as they do now, but they wont 
have to manually configure cmake. 
My fix is only a cmake fix, not an OSG functionality fix. It lets the user 
define OPENGL_PROFILE before pressing "Configure" in windows cmake and 
automatically sets up the disabling of deprecated functions in OSG. Without it 
you have to know and manually select what you think should not be in the GL3 
profile. 
Robert already has that defined in CMake, in windows it is just never called 
unless you have the old gl3.h header...which no one does anymore. So this is 
more of an update. 

I'll make a pull request, and let Robert look at it...
