[vtkusers] Fix Ubuntu 14.04 VTK 6.1 compiling issue

I had the same issue today, on both VTK 6.1 and the current git HEAD. I use
the NVidia driver version 343 (gl headers dated august 2014). However, a
colleague of mine compiles VTK fine when using an older driver (331 /
january 2014).

I looked into the GL headers (/usr/include/GL/) and found that GLintptr now
is in use in glxext.h, this was not the case in the previous version.

My solution was to uncomment the define GLXEXT like this:

// define GLX_GLXEXT_LEGACY to prevent glx.h to include glxext.h provided by
// the system
#include "GL/glx.h"

#include "vtkgl.h"

in file


which causes glext.h to be included in glxext.h, thus providing the missing
type GLintptr.

This seems like a better solution than including vtkgl.h before GL/glx.h,
but I don't have the full picture here.

> Compiling fails, because "GLsizeiptr has not been declared".
> The issue is that "vtkgl.h" is included *after* "GL/glx.h" which needs
> the typedefs for the datatypes from "vtkgl.h".
> I simply swapped the two lines and VTK compiles. Appended a patch that
