[vtk-developers] glext.h and glxext.h on OSX

[Francois Bertel]

Hi,

We try to keep glxext.h in VTK up-to-date with the official file from
opengl.org ( http://www.opengl.org/registry/api/glxext.h )

Are you asking this question because you encounter some error or just
for a general recommendation?

In the first part of the file, there is something like:

/* glxext.h last updated 2008/10/22 */
/* Current version at http://www.opengl.org/registry/ */
#define GLX_GLXEXT_VERSION 21

you can compare this part with the different versions of glxext.h
provided by your machine and by VTK.

Right now, the version does not matter too much but I recommend to
point to the one provided with VTK.
