 /* glcorearb.h replaces gl3.h. It is for use with OpenGL core
  * profile implementations.
  *
  * glcorearb.h last updated on $Date: 2012-09-19 19:02:24 -0700 (Wed, 19 Sep 2012) $
  *
  * RELEASE NOTES - 2012/09/19
  *
  * glcorearb.h should be placed in the same directory as gl.h and
  * included as
  * '<GL/glcorearb.h>'.
  *
  * glcorearb.h includes only APIs in the latest OpenGL core profile
  * implementation together with APIs in newer ARB extensions which can be
  * can be supported by the core profile. It does not, and never will
  * include functionality removed from the core profile, such as
  * fixed-function vertex and fragment processing.
  *
  * It is not possible to #include both <GL/glcorearb.h> and either of
  * <GL/gl.h> or <GL/glext.h> in the same source file.
  *
  * Feedback can be given by registering for the Khronos Bugzilla
  * (www.khronos.org/bugzilla) and filing issues there under product
  * "OpenGL", category "Registry".
