"   2007-08-30 (v1.5) 
"       * Added OpenGL ES 2.0 and EGL symbols
"          (thanks to Simon Hosie [sh1 at broadcom dot com]).
"       * Added following variables: 
"           c_opengl_no_gles2 - turns off GLES2 highlighting
"           c_opengl_no_egl - turns off EGL highlighting
"       * Now version numbering is a bit screwed =)
"
"   2003-11-07 (v1.4.1) 
"       * Added GLUT support
"          (thanks to Mathias Gumz [gumzat at cs dot uni-magdeburg dot de]).
"       * Added following variables: 
"           c_opengl_no_glu     - turns off GLU highlighting
"           c_opengl_no_glut    - turns off GLUT highlighting
"           c_opengl_no_ext_arb - turns off ARB extensions highlighting
"
"   2003-10-31 (v1.4) 
"       * Updated to OpenGL 1.4 ARB extensions for OpenGL Shading Language
"          (thanks to Eric Boumaour [zongo at nekeme dot net]).
"       * Now version number match OpenGL version.
"
"   2003-08-29 (v0.1)
"       Initial release
"
" TODO: add support for vendor specific extensions (NVidia and ATI at least)
